If a static android library lib1 has static_libs: ["lib2"] then the
R.class files for packages in lib2 will be merged into the jar for
lib1. If an app has lib1 in its static_libs it will get the R.class
files from lib2 through lib1, instead of regenerating the R.java
files with numbering that matches the resource table of the app.
Pass transtive static android library dependencies on the aapt2
command line so that aapt2 will always regenerate the R.java
constants for those packages.
Also extract the packages that have R.java files after each aapt2
invocation. This is not necessary for Soong, but is passed to
make to let it force regenerating the packages using
--extra-packages.
