Remove qtypetraits.h's contents altogether

So that QFlags can use an (un)signed int matching the
underlying type as identified by the compiler and not by us.

Requires fixing a few warnings about sign conversion due to
QFlags misusages in qtbase that were either plain wrong, or
were relying on the enum being backed by an (un)signed int
when it wasn't.

Keep qtypetraits.h in the source tree in order to prevent
source breaks if some downstream #includes it (note however
that it did not contain any public API).
