ipa: raspberrypi: Rename SdnStatus to DenoiseStatus

This change is in anticipation of the addition of a DenoiseAlgorithm
base class which the SDN class will derive from. We want to match the
metadata object name with the base class algorithm name.

This renames:
- SdnStatus metadata object to DenoiseStatus
- "sdn.status" metadata string key to "denoise.status"
- sdn_status.h header file to denoise_status.h
