EyeAdaptationBuffer crosses graphics to compute queue without synchronization

Hi Stephen!

Thanks for the reply! We are on 5.5.4 and experiencing this issue.

The commit from the other thread is here: https://github.com/EpicGames/UnrealEngine/commit/538605b4c33e92a51095c1ea87c8bbe2696fcbcf.

However, it does not look like this commit is in the release branch that is currently at 5.5.4. https://github.com/EpicGames/UnrealEngine/blob/release/Engine/Source/Runtime/D3D12RHI/Private/D3D12CommandContext.cpp.

I can pull the commit into our branch and test it, but 5.5.4 does not have the fix yet.

Thanks!
