[SHT_LLVM_BB_ADDR_MAP][AsmPrinter] Implements PGOAnalysisMap emitting in AsmPrinter with tests. (#75202)

Uses machine analyses to emit PGOAnalysisMap into the bb-addr-map ELF
section. Implements filecheck tests to verify emitting new fields.

This patch emits optional PGO related analyses into the bb-addr-map ELF
section during AsmPrinter. This currently supports Function Entry Count,
Machine Block Frequencies. and Machine Branch Probabilities. Each is
independently enabled via the `feature` byte of `bb-addr-map` for the given
function.
