libcamera: v4l2_subdevice: Add stream support to get/set functions

Extend the V4L2Subdevice API with stream support for the functions that
get and set formats and selection rectangles. Add a Stream structure to
identify a subdev pad and stream, and use it to extend the V4L2Subdevice
functions that get and set formats and selection rectangles with stream
support.

To preserve the existing pad-based API, implement overloaded functions
that wrap the new stream-based API. This allows callers that are not
stream-aware to use a simpler pad-based API, instead of having to
explicitly set the stream number to 0 in all API calls.
