lavfi/framesync: avoid forcing frame writability unnecessarily Callers of ff_framesync_get_frame() generally do not expect the result to be writable, those that do (e.g. ff_framesync_dualinput_get_writable()) ensure writability themselves. Significantly reduces memory consumption in complex graphs with framesync-based filters (e.g. scale, ssim).
