Convert more of art to Android.bp

Relanding I1b10f140e17dd5e12a9d7f6a29d47cf61f5bf6ef, with fixes to
compile dalvikvm32 and dalvikvm64, and add them as dependencies of
tests.  Also fixes HOST_PREFER_32_BIT by moving the override from the
defaults, which are not used by everything in art, to the art_cc_binary
module type.

Test: rm -rf out/host; m -j HOST_PREFER_32_BIT test-art-host; m -j test-art-host
