The driver version is logged and checked after the RHI instance is created, before calling GDynamicRHI->Init(). This worked on D3D11 and 12 without many changes because those RHIs select the adapter before the Init call, so they can fill in the information necessary for GetGPUDriverInfo() before Init. However, the Vulkan RHI init code had to be restructured quite a bit to do the same thing.
Also removed some obsolete hardcoded driver version checks from the Vulkan RHI, since we have better checks in RHIDetectAndWarnOfBadDrivers().

This change includes significant refactor work performed in //UE5/Dev-ParallelRendering. A brief summary of the work is as follows:
Refactored RHI command lists
- Removal of the "immediate" async compute command list
- Introduced an "active pipe" on each command list, allowing RHICmdLists to record work for either graphics or async compute. Pipes can be selected using the SwitchPipeline() function, or the FRHICommandListScopedPipeline helper.
- New explicit command list submission RHI API (RHIFinalizeContext, RHISubmitCommandLists). The IRHICommandContextContainer type has been removed.
- Explicit GPU submission is automatically appended to the immediate command list when it is dispatched to the RHI thread.
Platform RHI implementations
- The new submission API has been implemented across all platforms. Some platforms required a significant refactor.

Fixed include paths to be relative to the private or public folders.
Hid or removed includes that reached into other private module folders.
Updated PublicInclude paths when necessary.

By default Lumen is disabled for Scene Capture to save memory, but can be enabled via post process override settings. The memory usage display was important when adding this feature, to give feedback to the user of the memory impact for enabling Lumen. It's also just generally useful besides. Lumen costs 340 MB to enable if view specific Lumen scene data is enabled at low quality (half resolution page buffer), or 640 MB at high quality (full resolution page buffer). Besides memory statistics in the Texture Editor, there is an editor specific command which dumps per-resource sizes to log (r.SceneCapture.DumpMemory), useful for investigating where the memory is going.
Lumen requires persistent state to function properly, so Lumen is disabled if bCaptureEveryFrame and bAlwaysPersistRenderingState are both false. I decided not to allow Lumen for Scene Capture Cube, due to high memory cost, poor CPU performance, and lighting seams across the faces. I'm hoping in the future to run Scene Capture Cube as a single scene render call (effectively 6-way split screen for the 6 cube map faces), and have certain rendering passes run as a single omnidirectional pass. Perhaps Lumen could use a single radiance cache for all 6 faces, rather than 6 separate caches, reducing memory, significantly improving performance, and hopefully solving lighting seams.
I rounded out the set of functions that handle per-view VSM and Lumen caches, to include functionality to remove the caches (necessary to allow the per-view Lumen cache to be toggled back off), and query their presence.

- RHISupportsMultiviewport made to work on relevant shader platforms.
- RHISetStereoViewport implemented
- Unused outputs removal fixed to always consider viewport index used.
- Renamed confusing terminology (multiview -> multiviewport).
- Added a CVar (vr.MultiViewport) to force disable
- Added a canvas output to know the method in non-Shipping
