Rename common to android
Rename the "common" package to "android", because common is too
generic. Also removes all android.Android naming stutter.
Ran:
gomvpkg -from 'android/soong/common' -to 'android/soong/android'
gorename -from '"android/soong/android".AndroidModuleContext' -to 'ModuleContext'
gorename -from '"android/soong/android".AndroidBaseContext' -to 'BaseContext'
gorename -from '"android/soong/android".AndroidModuleBase' -to 'ModuleBase'
gorename -from '"android/soong/android".AndroidBottomUpMutatorContext' -to 'BottomUpMutatorContext'
gorename -from '"android/soong/android".AndroidTopDownMutatorContext' -to 'TopDownMutatorContext'
gorename -from '"android/soong/android".AndroidModule' -to 'Module'
