This PR fixes dSYM collection for frameworks specified in the
`frameworks` attribute of `ios_ui_test` targets.

Currently, while framework binaries are properly made available to test
targets, their corresponding dSYM files are not collected in the test
bundle's debug symbol directory. This causes missing debug symbols when
debugging test failures that involve framework code.

The fix ensures that dSYMs from framework dependencies are included
alongside dSYMs from regular dependencies specified in the `deps`
attribute.

Consume fix for selecting simulators from
google/xctestrunner#67

- Bumped stardoc and removed overrides
- Bumped protobuf to a version without a transitive dependency on a
version of aspect_bazel_lib that invoked
--incompatible_use_toolchain_transition
- Bumped rules_cc to 0.1.2 to fix docs, corrected stardoc dep labels,
updated docs

Closes: #2502

There is no need to generate an air file for each metal file.
Metal CLI can do it behind the scene (as per Apple's
[docs](https://developer.apple.com/documentation/metal/generating-and-loading-a-metal-library-symbol-file?language=objc#Generate-a-Symbol-File-with-a-Single-Command)),
so just one CLI call is sufficient to build entire metallib.
The new implementation a much simpler as well as makes it easier to pass
additional flags (such as "generate debug symbols" as described in the
original issue).

- remove mentions of `WORKSPACE`
- polish up the blocking, wording for consistency
- update language around rules_xcodeproj

Fixes #2737

bazelbuild/bazel@02df95c has removed
repo_mapping from stardoc's data source, so it's no longer emitted to
generated docs. This PR fixes CI to reflect. Note that running stardoc
without using `last_green` Bazel produces different output, because of
this change.
