Merge libart and libart-compiler into a single library

Rename old libart to 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.
Remove JitLoadTest, since `jit_create` (previously `jit_load`) function
is guaranteed to exist in `libart`.

After this change libart-compiler will have access to all libart-runtime
symbols. This will allow to hide more symbols from libart-runtime.

ART APEX size before and after:
X86   : 29,748.00 KiB -> 29,648.00 KiB (-100.00 KiB, -0.34%)
X86_64: 49,148.00 KiB -> 48,928.00 KiB (-220.00 KiB, -0.45%)
