Fix cdex bugs to enable ART_DEFAULT_COMPACT_DEX_LEVEL=fast tests passing
Compute dex checksum for compact dex generation. Handle input vdex
by not aborting in oat_writer, instead just avoid generating compact
dex for the input vdex case.
Re-enabled some compact dex tests.
Bug: 63756964
Test: ART_DEFAULT_COMPACT_DEX_LEVEL=fast test-art-host
