Enable ART properties modularization

ART is becoming a module and we need to be able to add new properties
without modifying the non updatable part of the platform:

- convert ART properties to use prefix in the namespace of
[ro].dalvik.vm.
- enable appdomain and coredomain to read device_config properties
that configure ART

Test: boot
