Teresa Johnson b1926f308f Restore "[MemProf] Memprof profile matching and annotation" ...

This reverts commit 794b7ea960, and
thus restores commit a212d8da94, and
follow on fixes 0cd6763fa9,
e9ff53d42f, and
37c6a25e9a.

Use a hash function (BLAKE3) instead of hash_combine/hash_code which are
not guaranteed to be stable across executions.

Additionally, it adds a "REQUIRES: x86_64-linux" to the tests that have
raw profile inputs to avoid failures on big endian bots.
