virtual-monitor: Never reuse mode IDs

Browse Source 
We'll change mode's on-demand so using IDs identical to the virtual
monitor ID would mean IDs didn't change when changing mode, and that is
rather unintuitive. IDs don't mean much anyhow, just make them grow
within the realm of a 63 bit unsigned integer, as the 64th bit means its
a virtual mode ID. Making sure the ID is in the virtual mode namespace
is handled by meta_crtc_mode_virtual_new().
