marius doerner 9a1ece2612 [clang] Clear NeedsCleaning flag after ExpandBuiltinMacro (#133574) ...

After builtin macro expansion in `Preprocessor::ExpandBuiltinMacro` the
result token may have the `Token::NeedsCleaning` flag set which causes
an assertion failure later on when the lexer retrieves the spelling of
the token in `getSpellingSlow`.

This commit adds an `Tok.clearFlag(Token::NeedsCleaning)` call to the
end of `ExpandBuiltinMacro`.

Closes #128384
