[media] soc-camera: Support user-configurable line stride
Add a capabilities field to the soc_camera_host structure to flag hosts that support user-configurable line strides. soc_camera_try_fmt() then passes the user-provided bytesperline and sizeimage format fields to such hosts, and expects the host to check (and fix if needed) the values.
