Send cancel events to the correct display when mirroring

When a display is mirrored, such as when screen recording is enabled,
there will be clones of the input windows on the mirrored display that
are on the mirror display.

When there is a stream of input going to the channel through one of
those windows and that stream should be canceled, the generated cancel
event should be sent to the correct window on the correct display.
