[BOLT][NFCI] Use FileSymbols for local symbol disambiguation (#89088)
Remove SymbolToFileName mapping from every local symbol to its
containing FILE symbol name, and reuse FileSymbols to disambiguate
local symbols instead.
Also removes the check for `ld-temp.o` file symbol which was added to
prevent LTO build mode from affecting the disambiguated name. This may
cause incompatibility when using the profile collected on a binary built
in a different mode than the input binary.
Addresses #90661.
Speeds up discover file objects by 5-10% for large binaries:
- binary with ~1.2M symbols: 12.6422s -> 12.0297s
- binary with ~4.5M symbols: 48.8851s -> 43.7315s
