libcamera: Add user Transform to CameraConfiguration

Browse Source 
Add a field to the CameraConfiguration (including the necessary
documentation) to represent a 2D transform requested by the
application. All pipeline handlers are amended to coerce this to the
Identity, marking the configuration as "adjusted" if something
different had been requested.

Pipeline handlers that support Transforms can be amended subsequently.
