Use and export proguard flags from static dependencies

Browse Source 
Export proguard flags from Android library modules, and use them
from static dependencies in Android apps when running proguard.
Also export them to Make.

Unlike Make, which concatentates all the exported flags from
dependencies, Soong dedups exported flags files.

Test: m checkbuild
