server: add monitors_config support

a SpiceMsgDisplayMonitorsConfig is sent on two occasions:
 * as a result of a spice_qxl_monitors_config_async
 * whenever a client connects and there is a previously set monitors
   config

Sending the new message is protected by a new cap,
SPICE_DISPLAY_CAP_MONITORS_CONFIG

More elaborately:
spice_qxl_monitors_config_async receives a QXLPHYSICAL address of a
QXLMonitorsConfig struct and reads it, caching it in the RedWorker, and
sending it to all clients. Whenever a new client connects it receives
a SpiceMsgDisplayMonitorsConfig message as well.
