ipa: raspberrypi: Add a DenoiseAlgorithm class to the Controller

Browse source 
This denoise algorithm class will be used to pass in the user requested
denoise operating mode to the controller. The existing Denoise
controller will derive from this new DenoiseAlgorithm class.

Add a denoise mode field in the denoise status metadata object for the
IPA to use when configuring the ISP.
