QTypeInfo: add detection for Clang's __is_trivially_relocatable
Types marked with [[clang::trivial_abi]] are considered to be trivially
relocatable for Clang. This is ABI compatible, since in Qt 6 we can
change the value of QTypeInfo::IsRelocatable "after the fact" -- it
simply means that code that doesn't get recompiled is pessimized.
