ui/gtk: expose gd_monitor_update_interval

The gd_egl_refresh function, as the name suggests, is responsible for
refreshing displays when using EGL graphics with QEMU's GTK UI. This is
a perfect candidate for a function to update the refresh rate in.

Since gd_monitor_update_interval is inaccessible from the gd_egl_refresh
function, we need to expose/globalize it in the include/ui/gtk.h file.
