Windows QPA: Improve Pointer Pen events translation

Compute QPointF hi-res screen coordinates based on the HIMETRIC values
contained in the native message. This gives the same high-precision
screen coordinates as what the old WinTab handler supported.

Add the possibility to not synthesize mouse events if the platform
plugin option DontPassOsMouseEventsSynthesizedFromTouch is set,
just like we do for finger touches. This makes it possible to have
clean Pen events without mouse duplicates for an application that
handles both input types in parallel.

Add raw event logging when the platform verbose level is >1.
