Since Android Testing is broken with Bazel 4.2.1 for a long time, I'll disable it in Bazel downstream. Android testing will no longer get any test coverage with Bazel@HEAD, but we can re-enable it in downstream when this issue is fixed.

Research direction

Start by reproducing the Bazel 4.2.1 Android build failure, then inspect ui/espresso/IntentsAdvancedSample/BUILD.bazel at line 29 and ImageViewHasDrawableMatcher.java. Confirm why BoundedDiagnosingMatcher is unavailable and verify that Android testing builds successfully again so downstream coverage can be re-enabled.
