[BOLT] Match functions with call graph (#98125)
Implemented call graph function matching. First, two call graphs are
constructed for both profiled and binary functions. Then functions are
hashed based on the names of their callee/caller functions. Finally,
functions are matched based on these neighbor hashes and the
longest common prefix of their names. The `match-with-call-graph`
flag turns this matching on.
Test Plan: Added match-with-call-graph.test. Matched 164 functions
in a large binary with 10171 profiled functions.
