The simple pipeline handler rejects devices that have multiple capture
video nodes. There's no real reason to do so, a more dynamic approach is
possible as the pipeline handler already locates the video device by
walking the media graph.
Rework the match sequence by skipping any check on the video nodes, and
create the V4L2VideoDevice for the media entity at the end of the
pipeline when initializing the camera data. The V4L2VideoDevice
instances are managed by the pipeline handler itself, to avoid creating
separate instances in the camera data if multiple sensors are routed to
the same video device.

This new pipeline handler aims at supporting any simple device without
requiring any device-specific code. Simple devices are currently defined
as a graph made of one or multiple camera sensors and a single video
node, with each sensor connected to the video node through a linear
pipeline.
The simple pipeline handler will automatically parse the media graph,
enumerate sensors, build supported stream configurations, and configure
the pipeline, without any device-specific knowledge. It doesn't support
configuration of any processing in the pipeline at the moment, but may
be extended to support simple processing such as format conversion or
scaling in the future.
The only device-specific information in the pipeline handler is the list
of supported drivers, required for device matching. We may be able to
remove this in the future by matching with the simple pipeline handler
as a last resort option, after all other pipeline handlers have been
tried.

The EXIF IFD is incorrectly chained to IFD 0 in addition to being a
referenced as a sub IFD through the EXIFIFD tag. While the libtiff API
doesn't clearly document why this happens, inspection of the
TIFFWriteDirectory() source code show that the function treats the IFD
being written as containing an image, which isn't correct for the EXIF
IFD. Use TIFFWriteCustomDirectory() instead, which fixes the problem.

The CameraSensor class assumes that camera sensors support the exact
same list of sizes of all media bus codes. While allowing a simpler API,
this assumption is incorrect and is blocking usage of some camera
sensors.
Relaxing the constraint is possible without changes to the CameraSensor
API syntax, but requires changing its semantics. The sizes() function
now returns the list of all sizes for all media bus codes, and the
getFormat() function now searches in all supported media bus codes. The
former is likely not the most useful option for pipeline handlers, but
the sizes() function is currently unused. Designing a better API will
require inspecting current and expected future use cases in pipeline
handlers to determine proper heuristics.
While at it, fix a small typo in an unrelated comment.
