ipa: rpi: Add new algorithms for PiSP

Add new CAC, HDR, Saturation and Tonemapping algorithms.

Add a new Denoise algorithm that handles spatial/temporal/colour denoise
through one interface. With this change, the old SDN algorithm is now
considered deprecated and a warning message will be displayed if it is
enabled.
