Convert libart and dependencies to Android.bp
Re-landing I73839046a5a53eb34cd28eea53149911c568e411, with fixes for mac
build (only apply -Wl,--keep-unique to device x86 builds), typo in
checking for ART_HEAP_POISONING environment variable, and removing
-Wframe-larger-than for debug builds.
Test: mma -j, m -j test-art-host
