Add a debanding property to Viewport

Browse Source 
It can be enabled in the Project Settings
(`rendering/quality/screen_filters/use_debanding`). It's disabled
by default as it has a small performance impact and can make
PNG screenshots much larger (due to how dithering works).
It will also slightly brighten the scene's dark areas.

As a result, it should be enabled only when banding is noticeable enough.

This closes #17006.
