[NFC]Rename InstrProf::getFuncName{,orExternalSymbol} to getFuncOrValName{,IfDefined} (#68240)

- This function looks up MD5ToNameMap to return a name for a given MD5.
https://github.com/llvm/llvm-project/pull/66825 adds MD5 of global
variable names into this map. So rename methods and update comments
