QtGui: compile-optimize inline swap functions

Instead of using the overly-generic qSwap() monster, use

- qt_ptr_swap() for swapping raw pointers
- member-swap for swapping smart pointers
- std::swap() for swapping scalars

In QtCore, this has proven to give a nice reduction in compile time
for Qt users, cf. b1b0c2970e480ef460a61f37fa430dc443390358.
