android: camera_device: Generate RAW resolutions
The resolutions supported for the RAW formats cannot be tested from a list of known sizes like the processed ones. This is mainly due to the fact RAW streams are produced by capturing frames at the CSI-2 receiver output and their size corresponds to the sensor's native sizes. In order to obtain the RAW frame size generate a temporary CameraConfiguration for the Role::StillCaptureRAW role and inspect the map of StreamFormats returned by the pipeline handler.
