Add an ability to exclude files from final binary produces by android_application

[nkoroste]

Gradle supports excluding artifacts from modules using the exclude keyword. This functionality is used across the Android ecosystem to exclude artifacts from the final APK mainly to reduce app size.

This PR adds new excludes attribute to android_application which supports a list of regex file patterns to exclude from the final binary (aab).

Is it not feasible to clean up your build dependencies to only include artifacts that you expect to be included in your final aab? Can you share an example usecase for the type of artifact you would want to exclude?

Sorry somehow missed your reply, here is a list of things we typically exclude
