This improves how the editor deals with displays that have different capabilities (some with HDR, others without).
Centralize where the CVars are accessed
Have the swapchain created in SDR when shown on a SDR display
Make sure color gamut matches the one supported by the platform/swapchain.
Allow Movie scene capture to override the gamut/output format to keep existing behaviour (MovieSceneCapture relies on swapchain data)

This allows lens flares to work with FFT bloom without introducing additional memory bandwidth costs in the tonemapper.

- Image exposure is locally adjusted by decomposing luminance of the frame into a base layer and a detail layer.
- Base layer contrast can be reduced while preserving detail.
- Support blending with gaussian blurred luminance as proposed in Advances in Real-Time Rendering in Games 2021.
- Controls in PostProcessVolume.
- r.LocalExposure cvar to control whether local exposure is supported.
- Visualization mode in "Show->Visualize->Local Expsoure". Multiple modes controllable using r.LocalExposure.VisualizeDebugMode.
- Bilateral grid generation not yet optimized. Optimization should include increasing depth of grid to match histogram size so that global histogram can be generated from grid.
- Added option to use mirror address mode in PostProcessWeightedSampleSum, since black border adds noticeable vignetting to the blurred luminance.
