Fixed crash due to bCachedRaytracingDataDirty not being initialized.
- the flag used to only affect a code path used by nanite coarse meshes in which it didn't cause a crash.
- however now it's used more generally resulting in a crash.
Note: Swarm is down, committing on behalf of Tiago Costa

* Fixes FCachedMeshDrawCommandInfo::MeshPass bitfield when EMeshPass::Num is exactly 1<<EMeshPass::NumBits and current compiler uses signed default enum storage
* Improved error message in FPrimitiveSceneInfo::CacheMeshDrawCommands that checks FCachedMeshDrawCommandInfo::MeshPass field

- Currently disabled by default (controlled using r.RayTracing.Nanite.Mode)
- Nanite triangle data is streamed out to temporary buffers and used to build BLASes.
- For hit shaders, instead of having to keep uncompressed vertex/index buffers, nanite data is referenced using an auxiliary buffer to identify page/cluster indices.
- BLAS build:
- Whenever a new Nanite page is installed/uninstalled, a rebuild of the associated mesh BLAS is requested.
- Compute shader is dispatched to stream out mesh data to temporary buffer as well as auxiliary data used by hit shaders.
- CPU then does a readback of part of the data to determine size of the BLAS etc and kicks off a BLAS rebuild.
- Added raytracing support to Nanite Vertex Factory.

- Also add the ability for clusters to be able to be sorted into up to two bins so that WPO-disabled clusters will render with the most optimal shaders possible.

- Static Meshes were caching mesh commands without having CacheMeshCommands set.
- Dynamic and Excluded primitives were also getting commands unecessarily cached.
- Unified some code.

- MeshPassProcessor create function takes feature level as create parameter
- MeshPassProcessor base stores the processor enum type (handy for reference and stat tracking per pass type)
When pass enum value is not available then EMeshPassType::Num is used for now

- Store cache flag in primitive scene proxy, default based on mobility initially
- When CPU invalidations of primitives that are cached as static happen, invalidate the entire primitive (all instances) and flip the flag to dynamic
- When GPU invalidations of primitives that are cached as static happen, mark a bit in a buffer that is read back to the CPU. In future frames, use the bits to find the associated primitive (if it still exists), swap it to dynamic and invalidate all of its instances
- Dynamic primitives are always cached as dynamic/movable
- Moved instance invalidation buffer ownership to cache manager (we don't need two copies at once)

- Removed scene render mem-mark among others. MemStack usage is now restricted to local scopes with known marks.
- Render resources with destructors are allocated using the FSceneRenderingBulkObjectAllocator on FSceneRenderer, which is deleted when the scene render is.
