This closes #7459.

This changes the Babel compilation targets to exclude IE 11,
which results in significant payload size savings.

This includes seemingly-unrelated changes because of dependency updates.

Allow expressing `meta` and `env` blocks as map attributes as well.

`env` and `meta` should support arbitrary key and values, yet hcl2
restricts the keys to valid identifiers. For example, block attribute
identifiers may not contain dots, `.`, which frequently used in meta
fields, and sometimes in environment variable fields.

By adding attribute syntax support, we maintain backward compatibility and relax the block attribute key restrictions. This change attempts to parse `env`/`meta` both as an attribute and as a
block.

Additionally, the change allows better expressivity for env/meta blocks, using
functions and for expressions. For example, one can reuse a set of environment variables for
multiple tasks, using a local `common_envs` value:

```hcl
env = merge(local.common_envs, {"more_env_key", "..."})
```

Note that the map/attribute compatibility workaround is currently a pattern we recommend for driver config blocks: https://www.nomadproject.io/docs/job-specification/hcl2#blocks . :( Sadly, the document isn't accurate, as only `meta` appearing inside driver config was handled in 1.0.1.

Closes https://github.com/hashicorp/nomad/issues/9606

As pointed out by Nick Ethier, if a node was ineligible before
it went down, downness should be displayed, not ineligibility.

The region will naturally be appended to URLs via
token.authorizedRequest but agent members includes all servers across
all regions so relying on the application-level region isn't good
enough.

UI: Use server-sent error messages when applicable

When the error is actually a 403, an ACL error is appropriate, but when
it isn't, fallback on what the API returns.

Automatically detect ACL errors
Provide a generic error message as a fallback
