Move most of runtime/base to libartbase/base
Enforce the layering that code in runtime/base should not depend on
runtime by separating it into libartbase. Some of the code in
runtime/base depends on the Runtime class, so it cannot be moved yet.
Also, some of the tests depend on CommonRuntimeTest, which itself needs
to be factored (in a subsequent CL).
Bug: 22322814
Test: make -j 50 checkbuild
make -j 50 test-art-host
