utils: raspberrypi: ctt: Update noise/sharpness tuning

Browse Source 
The default noise/sharpness/gamma values are updated to reflect the
latest camera tuning work.

- Denoise is increased when not using temporal denoise.
- Denoise is reduced when benefitting from temporal denoise.
- Over-sharpening is reduced.
- High contrast gamma is slightly reduced.
