Merge libart and libart-compiler into a single library

Rename old libart into libart-runtime
Build libart-runtime and libart-compiler separately as static libraries
This is required to support PGO (compiler) and AFDO (runtime) without
mixing them
Combine libart-runtime and libart-compiler into libart with
whole-archive linking

This change negates all size savings from libart-compiler
version script, it will be restored in a follow-up CL
