ext_image_copy_capture_v1: replace schedule_frame with request_frame

Browse source 
schedule_frame is only called when the client has submitted damage
and a new frame should be rendered immediately. schedule_frame is
not called when the capture client is waiting for the next frame
but hasn't submitted damage.

Sources implementing a rendering loop based on the capture rate
need to know when a capture client is ready to accept a new frame.
Such sources want to trigger a redraw if and only if (1) they are
dirty (their contents have changed) and (2) the capture client is
ready to accept a new frame.

Replace schedule_frame with request_frame, triggered each time a
client sends a capture request. A flag indicates whether the capture
client has submitted damage.
