  -----------
   [BOLT] Add sink block to flow CFG in profile inference (#95047)

Summary: Constructing an artificial sink block for the
flow CFG in stale profile inference to allow profile
inference to be run on CFGs with blocks that terminate
and have successors.

Testing Plan: Added infer_no_exits.test to verify that 
functions with exit blocks with a landing pad are 
covered by stale profile inference.
