Compilers that support 128-bit integer types usually don't have
support for 128-bit literals, so provide Q_(U)INT128_C macros and back
them with UDLs. This, of course, only works in C++, so until compilers
provide built-in literals that support C, too, that's all we get.
[ChangeLog][QtCore] Added Q_INT128_C() and Q_UINT128_C() macros to
create qint128 and quint128 literals in a platform-independent way.
Pick-to: 6.6 6.6.0
