Rémi Verschelde 372136fe75 Environment: Refactor code for readability + more 
- Makes all boolean setters/getters consistent.
- Fixes bug where `glow_hdr_bleed_scale` was not used.
- Split CameraEffects to their own source file.
- Reorder all Environment method and properties declarations,
  definitions and bindings to be consistent with each other
  and with the order of property bindings.
- Bind missing enum values added with SDFGI.
- Remove unused SDFGI enhance_ssr boolean.
- Sync doc changes after SDFGI merge and other misc changes.
