[v3,0/3] virtio-gpu: Respect UI refresh rate for EDID

Message

Let virtio-gpu be aware of the refresh rate. The EDID change is delivered with
display hotplugging, which should not happen too frequently. Because of that,
this moves the refresh rate to QemuUIInfo, whose change delivery is throttled.

The delivery throttling also affects xenfb and this change does not maintain
a seperate code path to avoid the throttling because the difference is little
if it xists. Usually the refresh rate of display does not change frequently and
most guests are not prepared for that anyway.

v3: Rebased to the latest QEMU.
