This is a follow up of 31ca5d035d
("Implements screen to screen move correctly").
As now we don't copy memory to implement moves there's no
reason to take into account these area for memory mappings
as memory is not accessed anymore.

Do not set SupportNonVGA field for device rev.4 and higher.
Then the class driver will not call miniport's procedure
StopDeviceAndReleasePostDisplayOwnership upon PnP stop.
QXL device modes are not compatible with VGA ones; the
driver in this procedure returns display information related
to QXL mode which later used by BasicDisplay driver and causes
it to show the screen incorrectly or fail to show it at all.

Doing some fast check on Windows 8.1 you could note that
moving windows you got a weird effect were windows were a
bit misaligned.
As documented in DXGKARG_PRESENT_DISPLAYONLY page
NumMoves/pMoves fields point to an array of screen-to-screen
moves while our code implemented them as an image drawing
(the same implementation of dirty rects) causing the weird
effect mentioned.
This patch implement the moves using QXL_COPY_BITS operation
instead of a QXL_DRAW_COPY fixing the issue and avoiding sending
image to the server making the move/scroll operations on the
guest faster (and taking less bandwidth).
It seems that Windows 10 doesn't send the move commands but
instead send only dirty rects so you can't note this problem
using Windows 10.

Windows disables hw pointer acceleration and draws the cursor
in frame buffer if the driver does not report pointer capabilities
in QueryAdapterInfo. In this mode OS usually does not send pointer
commands to the driver or does it with pointer set to invisible
state. This mode of operation consumes CPU time and device-to-host
traffic. Now we enable pointer hardware acceleration.

Starting with Windows Display Driver Model (WDDM) 1.2, if the
DevicePowerState parameter is set to PowerDeviceD0, the display miniport
driver should call DxgkCbAcquirePostDisplayOwnership to query the
information about the display mode.

When qxl revision is 3, the vga driver is the one that is running.
While installing the driver the function VgaDevice::HWInit
has displayInfo structure zeroed out. The displayInfo should be
initialized using DxgkCbAcquirePostDisplayOwnership and thus it
should be called before calling HWInit.
Please note that we can't just move the call to "DxgkCbAcquirePostDisplayOwnership"
before calling HWInit as the m_Id isn't initialized for QxlDevice until the call to HWinit is over.
This patch fixes a bug similar to the one found here:
https://bugzilla.redhat.com/show_bug.cgi?id=1202267
However this one occurs when installing the driver.

Framebuffer should only be used in VGA mode, as WDDM DOD
driver doesn't use the frame buffer (bar0), so no
reason to map in into memory. However the mode is only known
at runtime therefore framebuffer logic should be active when the
driver is operating in vga mode only.
There were rare BSOD failures when the mapping failed.

Interrupts seem to arrive to the driver before the initialization phase
is over (m_pHWDevice = NULL), in that case we can't handle interrupts yet.
Even when m_pHWDevice isn't NULL, other fields aren't necessarily fully
initialized till the StartDevice function has finished initialization,
thus the flag DriverStarted should be checked upon interrupts.
Note: There is no way provided by Microsoft to disable interrupts in WDDM
drivers.
