Added a FilterChain that can apply multiple filter steps to an APK file as it is being written to disk. The first filter applied is by ABI. If a library in the APK does not match the filter it is skipped. Added an AbiFilter that keeps files that are either not native libs or are for the set of wanted ABIs Test: ran unit tests locally Test: ran against an APK with ARM and x68 libs and diffed the results Change-Id: I3fb901d3de3513e85f2a2763a8e4487a28ed4881
