Do not enable SPICE when GTK or SDL are the selected display. Fixes #466

QEMU 7.0 introduces a change/regression where it is not possible to use GL accerlation via GTK/SDL displays and also bring up SPICE: https://gitlab.com/qemu-project/qemu/-/issues/1036

This patch prevents Quickemu from bringing up SPICE when GTK or SDK are selected as the display.
