Upgrade Android build infra (#3095)

Summary:
This includes a bunch of different things which I wanted to do separately, but it's all a massive Jenga Tower and you cannot remove a single piece.

- Litho upgrade
- Gradle plugin upgrade
- Remove storage permission as it apparently doesn't do anything above Android 10
- Upgraded build target to Android 12 because the new support lib/Kotlin stdlib required this which then caused the issue below to pop up
- Added "export=true" everywhere as this is now a blocking issue if you don't have it
- Upgraded to the LeakCanary2 plugin as version one no longer builds with an Android 12 target for the export reason
- Make CI run on JRE 11 because that's required by the new Gradle plugin
- Update internal CI to no longer define the SDK twice and use Java 11
