[Spice-devel] [spice-gtk]Add "monitors config position" capability.

[Sandy Stutsman]

This will allow Windows guests to determine if the client supports a
monitors_config message from a multi-monitor guest that is not
multi-hat.

It keeps commit:8b0cd321d5a4d08ccba5845c5f2206e6f8032c1d
from breaking if an updated win-qxl driver is paired with an older client.
