Convert Android.mk to Android.bp

See build/soong/README.md for more information.

Also moves pngtest to build as a test (installs to nativetest, builds
for 32-bit and 64-bit), and enable building it on the host.

Also moves NEON selection to be determined based on compiler flags.

Test: mmma -j external/libpng
Test: out/host/linux-x86/nativetest64/pngtest/pngtest
Test: m -j
