usb.rc: Advertise 360p and 480p support through UVC

Many host applications expect and ask for lower resolution streams when
streaming from a USB webcam. To support those applications, this CL
adds support for 640x480 and 640x360 streams.

Bug: 301170431
Test: Manually tested that the resolution is advertised and streamed.
