[USER32] GetQueueStatus() should not return 0 when passing QS_ALLINPUT flag that includes QS_RAWINPUT (#4115)
GTK applications call GetQueueStatus(QS_ALLINPUT), where QS_ALLINPUT
specifies the QS_RAWINPUT flag as well, when these are compiled for
Windows XP+, and they expect the call to succeed on this platform.

On one side, ReactOS does not currently support this flag at all, but
since it claims to be XP/2003-compatible, applications may implicitly
expect the flag to be supported by GetQueueStatus() and the function
*NOT* failing when this flag is set.
(Later GTK apps don't care and just call GetQueueStatus(QS_ALLINPUT)
that includes QS_RAWINPUT, and therefore would fail as well on e.g.
Windows 2000...)

Otherwise, an observable effect is that some versions of libgdk-win32-2.0.0.dll
enter into an infinite loop when calling GetQueueStatus(QS_ALLINPUT),
since this call always failed on ReactOS.

On the other side, however, we should honour our winetests that handle
the presence of the QS_RAWINPUT flag and behave differently accordingly.
But since we do not support QS_RAWINPUT yet, we should keep their old
behaviour where QS_RAWINPUT is unused.

Thus, in order to accomodate both sides, we don't fail the GetQueueStatus()
call, but just set the ERROR_INVALID_FLAGS last error and continue it.


This fixes CORE-15686, CORE-17551 and probably CORE-11850.
Fixes also all user32:TrackMouseEvent tests.
