Record @{Fast,Critical}Native in method's access flags.
Repurpose the old kAccFastNative flag (which wasn't actually
used for some time) and define a new kAccCriticalNative flag
to record the native method's annotation-based kind. This
avoids repeated determination of the kind from GenericJNI.
And making two transitions to runnable and back (using the
ScopedObjectAccess) from GenericJniMethodEnd() for normal
native methods just to determine that we need to transition
to runnable was really weird.
Since the IsFastNative() function now records the presence
of the @FastNative annotation, synchronized @FastNative
method calls now avoid thread state transitions.
When initializing the Runtime without a boot image, the
WellKnowClasses may not yet be initialized, so relax the
DCheckNativeAnnotation() to take that into account.
Also revert

as the annotation checks are now much faster.
