Update method exit hooks from JITed code to not use Stack visitor

Using NthCallerStackVisitor is expensive since that involves decoding
method header and other tasks that are reasonably expensive especially
when called on every method exit. When calling method exit hooks from
JITed code a lot of this information like the frame_size, calling method
are already known and can be directly passed to the method exit hook
instead of computing them.

Locally this change improves the performance by 70% on debuggable-cc
config of golem benchmarks.
