ART: Use libbase logging

Move most of our logging infrastructure over to system/core/base.
Retain VLOG.

Using unified Android infrastructure has two main advantages. First,
it reduces the complexity/maintenance burden in ART. Second, it
allows to detach logging for the cases where we do not want or need
a runtime, e.g., dexdump, the disassembler, etc. As a part of the
latter, libbase is also supported for all hosts (including Windows).

From a developer viewpoint, there are minor behavior changes for the
LOG statements (see above), but otherwise usage is the same. Explicit
severity enum items are in the android::base namespace now.
