Message:

pdmifs/DevVGA/DisplayImpl: add screen id to pfnVBVAReportCursorPosition.
bugref:9376: Complete hardware cursor implementation in VMSVGA.
vboxvideo in Linux passes cursor position information relative to a particular
screen, but we loose this information when we pass it on to the front-end.
Since no front-end has used the information yet this was not noticed. This
change fixes that and converts the co-ordinates to frame-buffer global ones
as early as possible.
