a52e1af7 - [ASTMatchers] Make isExpandedFromMacro accept llvm::StringRef (#167060)

[ASTMatchers] Make isExpandedFromMacro accept llvm::StringRef (#167060) We can use non-owning `StringRef` in `MacroName` parameter to avoid unnecessary copy because `MacroName` only used as an argument to `internal::getExpansionLocOfMacro` which already accept `StringRef`.
