* Update HCP Packer build labels argument

Previously when running a partial build on multi-cloud build template it
was found that build labels were only being applied at the creation for
the partially executed build. Leaving all other completed builds with
no HCP Packer build labels. This updates how incomplete builds are
loaded from the registry and ensure that any defined
hcp_packer_registry.build_labels are assigned to the build before
starting an actual Packer build.

Related to: #11573

* Add test case for overwriting build labels

* Update tests to call CreateInitialBuild for non-existing builds

* Rename test case to TestBucket_PopulateIteration

* Fix data race in PopulateIteration against mock service

* Add methods for managing builds on an Iteration

* Update Mock Service to be a bit more concurrent

It is a simple set of changes to make it work for the current testing
use cases. If we need to we can move the Called fields to counters or
re-architect the mock.

This change also fixes a race condition when appending to the Slice of
errs when calling PopulateIteration.

* Update test case descriptions

* Apply suggestions from code review

Only append to errs if err is not nil

```

* Update CreateIntialBuildForIteration to initialize each build with a new map

Previously upon creating the initial build the same map, which was
initialized for the build_labels argument was being shared across all
build images. This was causing an issue with labels being backed by the
same map for all builds. This change ensures that all builds get their
own map with any global build labels copied over during the initial creation.

Closes #11573

* Handle errors from bucket methods

* Update test cases

Initialize maps for bucket when calling NewBucketWithIteration

* allowing to set shell env vars from a key/value map.
* tests

This new map will work alongside the `environment_vars` but it allows using a
datasource value seamlessly. At validation, and because `environment_vars` was
an array of strings containing `KEY=value`, using datsources would not work,
because these values are not known yet and would evaluate to `<unknown>`. With
this, the value and the key can be unknown and will validate correctly for
datasources.

browsing through the documentation I was searching for the list of builders available. The obvious choice (builders page) didn't link to the list of builders and it took me a few minutes to find that. Adding a link to the plugins might speed up that bit and would avoid having to rescue to the search engine.

* evaluateLocalVariables: modify code for readability and some (not benchmarked) perfs

* Make default input variable type the DynamicPseudoType

This should be the default, and avoids a panic. This type can represent situations where a type is not yet known. Its meaning is undefined in cty.

* do not take Empty types from default value

* Update types.variables.go
