Added DexFileAsanRegistrar and necessary additions
This class was made so that sections of dex files
can be easily poisoned to check accesses to those sections.
In order to enable logging of reads to poisoned sections,
use art/tools/add_package_property.sh along with package
name on the device and art/tools/asan.sh.
