libcamera: v4l2_subdevice: Add V4L2Subdevice::Route structure
The V4L2Subdevice class deals with streams in two places:
- In routing tables, streams as expressed as a pad number and a stream
number in a v4l2_subdev_route instance.
- In the format and selection get and set functions, streams as
expressed using the Stream structure, which binds the pad number and
stream number.
Expressing streams in different ways requires pipeline handlers and
other helpers to convert between the two representations. This isn't
much of an issue yet as libcamera has little stream-aware code, but it
is expected to increasingly become a burden.
To simplify the API, introduce a V4L2Subdevice::Route structure that
mimicks the kernel v4l2_subdev_route structure but represents streams as
V4L2Subdevice::Stream instances. This will improve seamless integration
of routes, formats and selection rectangles.
