usb gadget: Add config for UVC in init
The UVC gadget requires some setup in configfs before it can be used by
the gadget HAL. This CL adds that setup to usb specific init.rc file.
Currently, UVC is setup to advertise mjpeg streams at 720p and 1080p at
60, 30, 24, and 15 fps each.
Bug: 242344221
Test: Manually tested that UVC is correctly set up on boot.
