The shader compiler will enable ISR or Mobile Multi-View in shaders, independent of whether they are actively engaged in stereo rendering.
But we _bind_ the instanced view UB when we think stereo is active. We can bind the instanced view UB even while doing mono rendering.

The previous control was just setting the D3D12 bindless heap sizes; now those sizes can be set and will only be used when the RHI controls are enabled.

This change allows users to opt-out of the engines default crash handling. Currently only implemented on Windows where the SEH code forwards the exception to externally registered handlers.
Thanks to Kristj�n Valur J�nsson for PR.

This logic took primitives with a material using static lighting and moved velocity writing to a second pass.
Seems like that is some old behavior and after asking around it isn't well known why we had it.
Anyway it's not good to pay the cost of that second pass, so removing that.

This allows to define a new dynamic scaling in the renderer with low amount of boiler plate:
DynamicRenderScaling::FHeuristicSettings GetDynamicTranslucencyResolutionSettings()
{
RenderingDynamicScaling::FHeuristicSettings BucketSetting;
BucketSetting.Model = RenderingDynamicScaling::EHeuristicModel::Quadratic;
BucketSetting.bModelScalesWithPrimaryScreenPercentage = true;
BucketSetting.MinResolutionFraction = ...
...
return BucketSetting;
}
DynamicRenderScaling::FBudget GDynamicTranslucencyResolution(TEXT("DynamicTranslucencyResolution"), &GetDynamicTranslucencyResolutionSettings);
And then simply define a scope to measure the GPU timing as such:
{
DynamicRenderScaling::FRDGScope DynamicTranslucencyResolutionScope(GraphBuilder, GDynamicTranslucencyResolution);
// add passes to GraphBuilder
}

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)
