bzlmod: Types for module extension *evaluation*
=================================================================

(https://github.com/bazelbuild/bazel/issues/13316)

* `ModuleExtensionContext`: The `module_ctx` object to be passed to the module extension's implementation function. For now, it only has 1 extra property `modules` which allows the module extension to access the dependency graph and all relevant tags.
* `StarlarkBazelModule`: The elements in `module_ctx.modules`. Each exposes the name and version of the module, and all the tags on it too.
* `TypeCheckedTag`: The type-checked version of `Tag`, which is exposed to Starlark through `StarlarkBazelModule` above. It contains all the attribute values passed to it in tags, but also has everything converted to native types and back to Starlark (so strings in `Tag` could become Labels in `TypeCheckedTag`).
