libcamera: rpi: Cache rawStreams and outStreams
Currently, the stream configuration is stored in two vectors, rawStreams and outStreams for convenience. However, these vectors are constructed in both platformValidate() and platformConfigure(). This change caches these vectors in the RPiCameraConfiguration class to construct them only once in platformValidate(). Pass a pointer to the current configuration to platformValidate() and platformConfigure() so that they can access the streams vectors.
