xkb: add hook to allow/deny AccessX key repeat

The xserver generates the key repeat by itself.

But when used with another server processing inputs first (e.g. a
Wayland compositor), the other server may be busy dealing with some
other things and not queue up key release events in time.

Add a vfunc in XkbSrvInfo to possibly add a check before re-emitting a
keypress event in the AccessX timer handler, so that the key repeat has
a chance to be denied if the server processing the input is not ready.
