Mingming Liu 3f78d89a2e [TypeProf][InstrFDO]Omit vtable symbols in indexed profiles by default (#96520) ...

- The indexed iFDO profiles contains compressed vtable names for `llvm-profdata show --show-vtables` debugging 
   usage. An optimized build doesn't need it and doesn't decompress the blob now [1], since optimized binary has the 
   source code and IR to find vtable symbols.
- The motivation is to avoid increasing profile size when it's not necessary.
- This doesn't change the indexed profile format and thereby doesn't need a version change.
