QWheelEvent: Make NoScrollPhase public

This reverts d5fde514106f5479f9c929c8a165aced4a1b2c84 and makes
that enum value the default for QWheelEvent::phase() with non
phase-aware mice.

[ChangeLog][QtGui] QWheelEvent::phase() returns NoScrollPhase with
non phase-aware mice. This is most mice and input devices except,
for now, Apple's trackpads and Magic Mouse.
