This does not truly change HDR since these platforms do not support toggling this at runtime. Instead we change the swapchain to be in SDR, and we end up in SDR mode with HDR output mode.
SDR in HDR mode is slightly darker on the TV, more than when comparing the screenshots of the swapchain. This is most likely due to the TV response, which needs to be investigated later on to see if we can somehow match the 2 properly.
In addition to the 2 CLs from main, this CL allows BP to change the CVar r.HDR.EnableHDROutput . On these platforms, the CVar is set with ECVF_SetByCode as soon as HDR was supported and calling EnableHDRDisplayOutput with ECVF_SetByGameSetting would get ignored

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)

-FPostProcessRectParams was still using the old FTexture2DRHIRef/GetTexture2D pattern rather than using FTextureRHIRef directly. This meant that it did not support 2DArray textures, like the VR swapchain, and caused an assert during a post-process blur on Lyra.

conversion to scRGB was happening twice in CompositeUIPixelShader: once during the LUT, and once during ST2084ToScRGB. We now rely only on the LUT to put us to the correct color space, just like we do during tonemapping
Make sure to use rec709 instead of rec2020 in editor, since this is the color space that is used by scRGB (PF_FloatRGBA backbuffer format)
Fixed UI composition to properly composite HDR elements (like the viewport) with the rest of the UI: we draw a black, 0-alpha rectangle as a proxy in the SDR pass for HDR elements, and we draw the HDR elements in their own rendertargets

This is causing an ensure to hit in Slate applications.
[FYI] Patrick.Boutot, Matt.Kuhlenschmidt
Original CL Desc
-----------------------------------------------------------------
Slate: Clear the uncached draw elements once they are batches and clear the batches elements once they are rendered. We do this to remove hard references to the Glyph Sequence from the previous frame. Cached draw elements are still cached. An old Glyph Sequence may still be a reference in a cached element but it is the responsibility of the SWidget to do the proper invalidation.
