Subject: [PATCH] Remove `google-java-format` from CI lint infrastructure

Summary:
All Android source files in ExecuTorch have been converted from Java to Kotlin as part of the ongoing Java-to-Kotlin migration. The `google-java-format` linter and CI job are no longer needed since there are no Java files left to format.

This removes:
- The `google-java-format` binary installation from the Docker linter image (`.ci/docker/common/install_linter.sh`)
- The `android-java-format` CI job from the lint workflow (`.github/workflows/lint.yml`)
