[roll] Roll fuchsia Revert "[build][bazel] Generate proper depfile for bazel_action() targets."

This reverts commit 23b41d32be69fed887b8c26df776b96ee0398d96.

Reason for revert: Still triggers too many Ninja "phony edge with no inputs doesn't exist" errors when checking for no-ops

Original change's description:
> [build][bazel] Generate proper depfile for bazel_action() targets.
>
> This is another attempt at fixing issue 117818, see [1] for a
> previous CL that had to be reverted because it created too many
> flaky Ninja no-op failures.
>
> The main ideas behind this CL are:
>
> - The bazel_action.py script, uses Bazel queries to determine
>   the list of implicit inputs from a top-level Bazel target,
>   which include both source files and build files.
>
> - Input files that belong to Bazel external repositories must
>   be mapped to locations outside of the Bazel output_base,
>   the logic to do so is detailed in a long technical note
>   in bazel_action.py and is ... sophisticated.
>
> - update-workspace.py is updated to generate content hash
>   files for many Bazel repositories. This was already the
>   case for @fuchsia_sdk and @internal_sdk, but now there
>   are also files for @fuchsia_clang, @prebuilt_clang,
>   @com_google_googletest as well, and all files are now
>   located under
>   $BAZEL_TOPDIR/workspace/generated_repository_hashes/<repo_name>.hash
>
> - Repository rules are updated to track said hash content
>   files (by calling repository_ctx.path(), which is enough
>   to force Bazel to record the association).
