e3393f147e android: camera_stream: Fetch format and size from configuration
Fetch the format and size of the libcamera::StreamConfiguration
associated with a CameraStream by accessing the configuration by
index.

This removes the need to store the libcamera stream format and sizes
as class members and avoid duplicating information that might get out
of sync.

It also allows to remove the StreamConfiguration from the constructor
parameters list, as it can be identified by its index. While at it,
re-order the constructor parameters order.

216030aa9d android: camera_stream: Retrieve Stream and Configuration
It's a common pattern to access the libcamera::Stream and
libcamera::StreamConfiguration using the CameraStream instance's
index.

Add two methods to the CameraStream to shorten access to the
two fields. This allows removing the index() method from the class
interface.

9e95d5e453 android: camera_device: Move processing to CameraStream
Move the JPEG processing procedure to the individual CameraStream
by augmenting the class with a CameraStream::process() method.

This allows removing the CameraStream::encoder() method.

160bb0998b android: camera_stream: Construct with Android stream
Pass the android camera3_stream_t, and a libcamera::StreamConfiguration
to identify the source and destination parameters of this stream.

Pass a CameraDevice pointer to the CameraStream constructor to allow
retrieval of the StreamConfiguration associated with the CameraStream.

Also change the format on which the CameraDevice performs checks to
decide if post-processing is required, as the libcamera facing format is
not meaningful anymore, but the Android requested format should be used
instead.

94c4d49ebe android: camera_stream: Add CameraStream::Type
Define the CameraStream::Type enumeration and assign it to
each CameraStream instance at construction time.

The CameraStream type will be used to decide if memory needs to be
allocated on its behalf or if the stream is backed by memory externally
allocated by the Android framework.
