JVMTI NotifyFramePop support

Adds support for the JVMTI can_generate_frame_pop_events capability.
This includes the NotifyFramePop function and the FramePop event.

We mark the interpreter shadowframes directly to get the events. This
relies on the fact that we never replace extant shadow-frames on the
interpreter stack to ensure that we can distinguish which jvmti-envs
requested the frame pops.
