[CONSRV]: Addendum to r63792: use a separate flag to filter the next-mouse-move event that MUST NOT appear before a button-up event (this appears to be somewhat VM-dependent). See code and CORE-8394 for more details.

* HACK FOR CORE-8394: Ignore the next mouse move signal

* HACK FOR CORE-8394 (Part 1):
*
* It appears that depending on which VM ReactOS runs, the next mouse
* signal coming after a button-down action can be a mouse-move (e.g.
* on VBox, whereas on QEMU it is not the case). However it is NOT a
* rule, so that we cannot use the IgnoreNextMouseSignal flag to just
* "ignore" the next mouse event, thinking it would always be a mouse-
* move signal.
*
* To work around this problem (that should really be fixed in Win32k),
* we use a second flag to ignore this possible next mouse move signal.
