- Require 64bit atomic support for Nanite by default now (r.Nanite.RequireAtomic64Support=1)
- Cleaned up a bunch of cvar component reattach callbacks to use lambdas instead of redundant global functions
- Added UStaticMesh::HasValidNaniteData() as a helper to check if an asset has valid Nanite data
- Improved Nanite unsupported on screen error message so that we don't asks the user to update GPU drivers on a console :)

- change matrix types for dynamic data to be explicitly using float
- wrapped update of vertex buffer to ensure type check
- When LWC mode is on, convert double based matrices to they float equivalent ( sub-optimal, but necessary for now until we have a better way )

[CL 16178381 by brett miller in ue5-main branch]
* Implemented thread safe object pool / free list allocator (FGeometryCollectionDynamicDataPool)
* Added Chaos stats for total transforms and changed transforms
* Removed TransformsAreEqual mechanism that caused full transform updates to occur unnecessarily for 2 subsequent frames, as the state wasn't stable until the previous 3 frames were stable. This was incredibly innefficient for GPUScene, etc..
* InitDynamicData now returns the data allocation (which can be null if not dynamic or if no transforms have changed), users of this now check if it's available, and either skip or fall back to the static/rest path otherwise
* Cleaned up some code paths by combining them with similar passes
* Removed tons of allocations, including heavy allocations/memcopies of transform data, even on stable frames (which were immediately deallocated right after allocation and setup of the dynamic data)
* Saves ~0.5 to 1.0ms of CPU time in heavy scenes
* Saves ~0.5ms of GPU time doing far less GPUScene updates
* Main optimization around this refactor is forthcoming in a followup CL (avoid calling MarkRenderTransformDirty in TickComponent).
