ART: Add support for patching and loading OAT files compiled with PIC

* Images (.art) compiled with pic now have a new field added.
* isDexOptNeeded will now skip patch-ing for apps compiled PIC
* First-boot patching now only copies boot.art, boot.oat is linked

As a result, all system preopted dex files (with --compile-pic) no
longer take up any space in /data/dalvik-cache/<isa>.
