color: keep track of supported primaries and transfer functions
In the next commits we'll start support clients that want to create image descriptions through params using the CM&HDR protocol extension. In order to do that, we'll have to expose the primaries and transfer functions that the color manager supports. So keep track of that. Signed-off-by: Leandro Ribeiro <leandro.ribeiro@collabora.com>
