android: camera_device: Initialize stream configuration

Browse source 
Initialize the stream configuration map by applying the Android Camera3
requested resolutions and formats to the libcamera Camera device.

For each required format test a list of required and optional
resolutions, construct a map to translate from Android format to the
libcamera formats and store the available stream configuration to
be provided to the Android framework through static metadata.
