Update stardoc for bzlmod

[luispadron]

This PR updates stardoc for use with bzlmod. This is required as the versions of stardoc on the registry require these stricter deps changes.

This updates our documentation (i.e. stardoc and bzl_library targets) to work in a similar way to rules_apple: https://github.com/bazelbuild/rules_apple/blob/master/apple/BUILD#L33

Each file we want documentation generated for defines it's own bzl_library with it's own set of deps. These target names are then used within the stardoc rule to generate documentation for each of them.

The main change is going from one giant bzl_library to multiple bzl_library.

Depends on the following stack:

• 777

• 778

I plan to PR two things before this PR is merged but that it depends on:

• Updating Bazel verison, we need >= 6.3.2 to fix issues with bzlmod and stardoc
• Update to use bazel_skylib's write_file rule vs our custom copy of it, reduces code duplication and amount of bzl_library needed to create
