dm: vdisplay: multi-local-mornitor support. 

To support full screen mode on one of multi-local-mornitor which
connected to service vm by monitor ID that customer specify. The
monitor ID is specified in acrn-dm's parameter like this:

virtio-gpu,geometry=fullscreen:monitor_id

For window mode, the vdisplay window always be shown on monitor 0,
because the customer can drag the window to anyone monitor. Besides, the
customer can set the monitor by x_off and y_off parameter like this:

virtio-gpu,geometry=<width>x<height>+<x_off>+<y_off>

v1->v2: Add note about zoom to pscreen width & height in fullscreen.
v2->v3: vdpy.width/height for window, used in host, vdpy.guest_width/
guest_height for guest framebuffer, used in guest.
