gtk: add spice_main_request_mouse_mode()

Send a SpiceMsgcMainMouseModeRequest message to request a mouse mode.

This allows to switch between client/absolute and server/relative mouse
modes.

This is necessary for some applications that require pointer
re-positioning, which we can't provide through a remote protocol easily
with client pointer (no such hardware-level message exists afaik).
