It needs real implementation for EnableMouseInPointer and IsMouseInPointerEnabled for Unity 6 WM_POINTER mouse support

[daemonserj]

Many new Unity 6 games use new input subsystem working with WM_POINTER events only without fallback to classic WM_MOUSE events.
So stubs for EnableMouseInPointer and IsMouseInPointerEnabled do not help.
But there is patch for Wine which catch WM_MOUSE events and convert to WM_POINTER
https://bugs.winehq.org/show_bug.cgi?id=53847
Please incorporate it if it's possible.
Thanks for your work!
