libcamera: pipeline: rkisp1: Implement color space support
Implement color space support in the rkisp1 pipeline handler, in the configuration generation, configuration validation and camera configuration. As all the processing related to the color space is performed in the part of the pipeline shared by all streams, a single color space must cover all stream configurations. This is enforced manually when generating the configuration, and with the validateColorSpaces() helper when validating it. Only the Y'CbCr encoding and quantization range are currently taken into account, and they are programmed through the V4L2 color space API. The primary colors chromaticities and the transfer function need to be configured in the ISP parameters buffer, and thus conveyed to the IPA, but the rkisp1 driver does not currently support tone mapping, so this will be done later.
