libcamera: libipa: camera_sensor: Add Sony IMX283 sensor properties

Provide the IMX283 camera sensor properties and registration
with libipa for the gain code helpers.

The test patterns exposed by the IMX283 do not map well to the current
set of test pattern controls supplied by libcamera. These are left
intentionally unimplemented.
