284919ef2e libcamera: camera_sensor: Expose the Bayer order
Pipeline handlers may need to know the Bayer order produced by the
sensor when a Transform is applied (horizontal or vertical flip). This
is currently implemented manually in the Raspberry Pi pipeline handler.
Move the implementation to the CameraSensor class to make it usable in
other pipeline handlers.

58bcddbdeb libcamera: camera_sensor: Test for read-only HBLANK with READ_ONLY flag
The CameraSensor class tests if the sensor HBLANK control is read-only
by comparing the minimum and maximum values, and documents this as being
a workaround for the lack of a read-only control flag in V4L2. This is
incorrect, as the V4L2 API provides such a flag. Use it to replace the
workaround.

2a6d432457 libcamera: camera_sensor: Reorder functions
The CameraSensor class has grown a lot since its creation, with many
functions added for different types of purposes. They are not grouped by
categories in the class definition, generating confusion when reading
the header file. Improve readability by sorting functions by category:

- Getters for static data (model, entity, focus lens, ...)
- Format and sensor configuration accessors
- Properties and controls (including test pattern mode)

Update the .cpp file accordingly.

9b1a2a8c8b libcamera: camera_sensor: Drop updateControlInfo() function
The CameraSensor::updateControlInfo() function is a wrapper around the
same function of the V4L2Subdevice class. It was meant to be called by
pipeline handlers that modify the sensor configuration directly,
bypassing the CameraSensor::setFormat() function. This never happened,
and the function is called once only, internally to the CameraSensor
class. No external users are foreseen, drop the function and call
V4L2Subdevice::updateControlInfo() directly.

2a0baf47eb libcamera: camera_sensor: Move related classes to subdirectory
In preparation for adding alternative implementations of the
CameraSensor class, move the code to a subdirectory to avoid cluttering
the main src/libcamera/ directory.
