ScreenCaptureKit: Set streams initial content rect during construction

The stream is reconfigured to a new resolution whenever a frame's
content rect differs from the previous frame's. The previous content
rect was left unset until the first frame arrived. If the window size
changes in between the stream starting and the first frame arriving,
we end up not reconfiguring the stream to match.

This patch makes us assign the content rect immediately when
constructing the stream.
