Android testing is broken with Bazel 4.2.1

まず Bazel 4.2.1 の Android ビルド失敗を再現し、次に ui/espresso/IntentsAdvancedSample/BUILD.bazel の29行目と ImageViewHasDrawableMatcher.java を調査してください。BoundedDiagnosingMatcher が利用できない理由を確認し、Android のテストビルドが再び正常に成功することを検証して、下流のカバレッジを再有効化できるようにしてください。

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.
