jian ru 1136b26cc3 Added a new approach to rasterize nanite clusters. It splits cluster material ranges into batches which are a collection of max 32 triangles and max 32 unique vertices. At runtime, it dispatches a single wave32 for each batch which uses cross-lane intrinsics to exchange vertex attributes instead of using LDS. The new shaders usually use less resources resulting in better overlap between HW and SW rasterization using async compute. Currently, the new method is only used on programmable HW rasterization shaders or the compute shader when the material is masked or uses PDO. ...

Public

Implemented DDC resource build for NaniteDisplacedMesh, including a stubbed out DisplaceNaniteMesh function that is just passthrough for now. Included exposing some of the static mesh and mesh description utilities to this plugin, and various other refactors.
