Replace Makefile with Android.bp. Remove duplication of protos in proto directory. Since we are now building the metrics_dump tool under Android, use frameworks metrics.proto directly. Also, reference cdm's wv_metrics.proto from the cdm directory instead of creating a subset in proto directory. bug: 161783052 bug: 170607430 Test: build m -j128 metrics_dump Test: metrics_dump [bugreport from adt-3-r.zip] Test: metrics_dump [bugreport from sabrina-q.gz] Test: metrics_dump --widevine [adb shell dumpsys media.metrics output] Change-Id: I82c7e723453ac2a6335cb2bb732a376d535b9ea3
