Use filegroup to simplify Android.bp for frameworks and its friends

Java and AIDL source files under frameworks/base are now modularized
using filegroup. Each filegroup has 'path' property set to the base
directory of the ssource files. This allows us to not rely on
aidl.[local_]include_dirs and srcs_lib_whitelist_dirs to get the base
directories.
