Windows QPA: Move the touch types API from platformheaders into QtGui

Change TouchWindowTouchType(s) to be (global) property of
QGuiApplication's native Windows interface since it does not make
sense to set it per window.

It appears the previous code setting the types per Window has never
worked since registerTouchWindow() bailed out due to the checks for
the flags TouchRegistered and IsTouchWindow() (setting in
HCBT_CREATEWND). In addition, registering windows for touch after
plugging in a device would not observe the setting.

Move the checks around to make this work.
