feat(windows/vdisplay): the driver leg of the mid-stream cursor-render flip

Browse Source 
Belongs to 493f4fae (which shipped only the crates/ side — this
packaging/ half was left unstaged, so the deployed driver silently
lacked the IOCTL and every flip died NOT_FOUND at dispatch):
IOCTL_SET_CURSOR_FORWARD dispatch + monitor::set_cursor_forward
(cursor_forward_on flag, resetup gate) + cursor_worker::
unsetup_hardware_cursor (empty-caps un-declare experiment).
