Pass core platform API policy property to ART 

When starting ART, read property
""persist.debug.dalvik.vm.core_platform_api_policy" and pass its value
on the command line. This enables users to enable core platform API
violation reporting on demand. Note that the settings take effect after
a reboot.

Test: compiles, boots, reporting observed
