[BOLT] Expose pseudo probe function checksum and GUID (#99389)

Add a BinaryFunction field for pseudo probe function GUID.
Populate it during pseudo probe section parsing, and emit it in YAML
profile (both regular and BAT), along with function checksum.

To be used for stale function matching.

Test Plan: update pseudoprobe-decoding-inline.test
