Android: Add golden AndroidManifest files.

Purpose is to have manifest changes reviewed so that unexpected changes
can't sneak into the merged manifest (ex. adding an aar dep that needs
extra permissions).

Any deviations from the golden files are printed for release builds
and will fail the build if the GN arg
check_android_configuration = true.
