Update go-cmp to prevent pointer arithmetic panics when using the race
detector.

closes #26516
Signed-off-by: Carlos Alexandro Becker <caarlos0@gmail.com>

helper/copy CopyDir was used heavily in tests. It differes from
internal/copydir in a few ways, the main one being that it creates the
dst directory while the internal version expected the dst to exist
(there are other differences, which is why I did not just switch tests
to using internal's CopyDir).

I moved the CopyDir func from helper/copy into command_test.go; I could
also have moved it into internal/copy and named it something like
CreateDirAndCopy so if that seems like a better option please let me
know.

helper/copy/CopyFile was used in a couple of spots so I moved it into
internal, at which point I thought it made more sense to rename the
package copy (instead of copydir).

There's also a `go mod tidy` included.

Fixes #26175

Update tests to match the fix in mitchellh/cli#71, which aligns MockUi
with BasicUi and allows newlines in user input.

We are not using the new ErrorWriter, added in mitchellh/cli#81, as it
does not appear to interact correctly with panicwrap. All error output
from CLI parsing will continue to appear on stdout, not stderr.

go-cty v1.6.1 fixes a panic in the `element` function when called with a negative offset.

We've not been using HIL in the main codepaths since Terraform 0.12, but
some references to it (and some supporting functionality in Terraform)
stuck around due to interactions with types we'd kept around to support
legacy shims.

However, removing the configs.RawConfig field from
terraform.ResourceConfig disconnects that subtree of dependencies from
everything else, allowing us to remove it. This is safe because the only
remaining uses of terraform.ResourceConfig are shims from values that
were already evaluated using the HCL 2 API, and thus they never need
the "just in time" HIL evaluation that ResourceConfig.interpolateForce
used to do.

We also had some HIL references in configs/hcl2shim that were previously
in support of the "terraform 0.12upgrade" command, but the implementation
of that command is now removed.

There was one remaining reference to HIL in a now-unused function in the
helper/schema package, which I removed entirely here.

This then allows us to remove the HIL dependency entirely, and also to
clean up some remaining old remants of the legacy "config" package that
we'd recently moved into the "configs" package pending further pruning.

dependencies: updating Azure/azure-sdk-for-go, Azure/go-autorest, hashicorp/go-azure-helpers, tombuildsstuff/giovanni

* updating `github.com/Azure/azure-sdk-for-go` to `v45.0.0`
* updating `github.com/Azure/go-autorest` to `v0.11.3`
* updating `github.com/hashicorp/go-azure-helpers` to `v0.12.0`
* updating `github.com/tombuildsstuff/giovanni` to `v0.12.0`

This is for consistency with other commands which use prompts, all of
which require "yes" rather than "y" to confirm.

We also migrate the login command to use UIInput, which now supports
securely asking for passwords or secrets via the speakeasy library.

* upgrade windows dependencies
* communicator/winrm: include configured timeout in winrm server

This new version permits omitting the space between the operator and the
boundary in a ruby-style version constraint, like ">1.0.0" instead of
"> 1.0.0".

* deps: Update github.com/hashicorp/aws-sdk-go-base@v0.5.0

Updated via:

```
$ go get github.com/hashicorp/aws-sdk-go-base@v0.5.0
$ go mod tidy
$ go mod vendor

Changes:

```
NOTES

* backend/s3: Deprecated `lock_table`, `skip_get_ec2_platforms`, `skip_requesting_account_id` arguments have been removed
* backend/s3: Credential ordering has changed from static, environment, shared credentials, EC2 metadata, default AWS Go SDK (shared configuration, web identity, ECS, EC2 Metadata) to static, environment, shared credentials, default AWS Go SDK (shared configuration, web identity, ECS, EC2 Metadata)
* The `AWS_METADATA_TIMEOUT` environment variable no longer has any effect as we now depend on the default AWS Go SDK EC2 Metadata client timeout of one second with two retries

ENHANCEMENTS

* backend/s3: Always enable shared configuration file support (no longer require `AWS_SDK_LOAD_CONFIG` environment variable)
* backend/s3: Automatically expand `~` prefix for home directories in `shared_credentials_file` argument

This adds supports for "unmanaged" providers, or providers with process
lifecycles not controlled by Terraform. These providers are assumed to
be started before Terraform is launched, and are assumed to shut
themselves down after Terraform has finished running.

To do this, we must update the go-plugin dependency to v1.3.0, which
added support for the "test mode" plugin serving that powers all this.

As a side-effect of not needing to manage the process lifecycle anymore,
Terraform also no longer needs to worry about the provider's binary, as
it won't be used for anything anymore. Because of this, we can disable
the init behavior that concerns itself with downloading that provider's
binary, checking its version, and otherwise managing the binary.

This is all managed on a per-provider basis, so managed providers that
Terraform downloads, starts, and stops can be used in the same commands
as unmanaged providers. The TF_REATTACH_PROVIDERS environment variable
is added, and is a JSON encoding of the provider's address to the
information we need to connect to it.

This change enables two benefits: first, delve and other debuggers can
now be attached to provider server processes, and Terraform can connect.
This allows for attaching debuggers to provider processes, which before
was difficult to impossible. Second, it allows the SDK test framework to
host the provider in the same process as the test driver, while running
a production Terraform binary against the provider. This allows for Go's
built-in race detector and test coverage tooling to work as expected in
provider tests.

Unmanaged providers are expected to work in the exact same way as
managed providers, with one caveat: Terraform kills provider processes
and restarts them once per graph walk, meaning multiple times during
most Terraform CLI commands. As unmanaged providers can't be killed by
Terraform, and have no visibility into graph walks, unmanaged providers
are likely to have differences in how their global mutable state behaves
when compared to managed providers. Namely, unmanaged providers are
likely to retain global state when managed providers would have reset
it. Developers relying on global state should be aware of this.

* vendor: upgrade go-cty dependency to 1.4.1

This upgrade fixes a panic with inconsistent object element types.

This includes a new TargetAddrs field on both Run and RunCreateOptions
which we'll use to send resource addresses that were specified using
-target on the CLI command line when using the remote backend.

There were some unrelated upstream breaking changes compared to the last
version we had vendored, so this commit also includes some changes to the
backend/remote package to work with this new API, which now requires the
remote backend to be aware of the remote system's opaque workspace id.

Upgrade hcl for hclwrite bugfixes, which will make 0.13upgrade more
reliable.

* update github.com/aws/aws-sdk-go to v1.30.9

* deps: github.com/aws/aws-sdk-go@v1.30.12

Reference: https://github.com/hashicorp/terraform/issues/24710
Reference: https://github.com/hashicorp/terraform/issues/24741

Changes:

```
NOTES:

* backend/s3: Region validation now automatically supports the new `af-south-1` (Africa (Cape Town)) region. For AWS operations to work in the new region, the region must be explicitly enabled as outlined in the [AWS Documentation](https://docs.aws.amazon.com/general/latest/gr/rande-manage.html#rande-manage-enable

). When the region is not enabled, the Terraform S3 Backend will return errors during credential validation (e.g. `error validating provider credentials: error calling sts:GetCallerIdentity: InvalidClientTokenId: The security token included in the request is invalid`).

ENHANCEMENTS:

* backend/s3: Support automatic region validation for `af-south-1`

This fixes several bugs:

- `substr("abc", 0, 0)` would previously return `"abc"`, despite the
  length argument being `0`. This has been changed to return an empty
  string when length is zero.

- `ceil(1/0)` and `floor(1/0)` would previously return a large integer
  value, rather than infinity. This has been fixed.
