* Existing calls to CreateSceneTextureShaderParameters and similar functions use "GetSceneTexturesChecked", which allows for the possibility that they are reached in a code path where scene textures haven't been initialized, and nullptr is returned instead of asserting. The shader parameter setup functions then fill in dummy defaults for that case. The goal was to precisely match the original behavior, which queried the RDG blackboard, and gracefully handled null if scene textures weren't there. This definitely appears to occur in FNiagaraGpuComputeDispatch::ProcessPendingTicksFlush, which can be called with a dummy scene with no scene textures. In the future, I may change this so dummy defaults are filled in for FSceneTextures at construction time, so the structure is never in an uninitialized state, but I would like to set up a test case for the Niagara code path before doing that, and the checks aren't harmful in the meantime.
* I marked as deprecated global functions which query values from FSceneTexturesConfig, but they'll still work with the caveat that if you use multi-view-family rendering, the results will be indeterminate (whatever view family rendered last). There was only one case outside the scene renderer that accessed the globals (depth clear value), which I removed, noting that there is nowhere in the code where we modify the depth clear value from its global default. I would like to permanently deprecate or remove these at some point. Display Cluster is the only code that's currently using the multi-view-family code path, and as a new (still incomplete) feature, third party code can't be using it, and won't be affected.

Hair strands now use the hair visibility output for injecting hitproxy & outline rendering, rather than rendering the hair strands geometry with a default material.

- View / InstancedView uniform buffers are now bound through RDG directly from the FViewInfo, or created on-demand for cases like jitter-free custom depth.
- Removed most of the custom persistent view uniform buffers. Left one in Lumen to be done in a later CL.
- ReflectionCapture uniform buffer is now bound at the RDG pass level.
