Removed FMeshBuilder::Build(UStaticMesh* StaticMesh, TArray<FStaticMeshBuildVertex>& Verts, TArray<uint32>& Indexes, TArray<FStaticMeshSection>& Sections, uint32& NumTexCoords, bool& bHasColors). It's somewhat danegous as it leaks mesh descriptors and isn't used anymore.

Added FMeshBuilder::BuildMeshVertexPositions. It replaces FMeshBuilder::BuildMesh(bool bBuildOnlyPosition = true) and does the minimal work which is required to extract vertex positions from a mesh descriptor.
...
This is later used to build static mesh derived data in cases where Nanite coarse mesh representation replaces original static mesh data and we can't depend on it. In extreme cases it lowers main thread derived data build time from ~7.5s to ~0.1s.

Generate mesh distance fields and Lumen card representation for Nanite meshes directly from the source mesh data. Nanite replaces static mesh data with a coarse mesh representation, which sometimes has holes in it or is not accurate enough. Building from the source data works around that issue and gets up the highest possible SDF/card quality. Unfortunately it also regresses static mesh import times by ~3-5% until we don't get async static mesh builds.
...
Mesh build numbers for Nanite meshes:
1701216 tris:
Static mesh build: 11.2s
Static mesh build for the SDF async task (added in this CL): 2.3s
Async SDF build: 0.7s
Async card rep build: 0.15s
5524435 tris:
Static mesh build: 36.4s
Static mesh build for the SDF async task: 6.2s
Async SDF build: 1.2s
Async card rep build: 0.5s
1146238 tris
Static mesh build: 10.5s
Static mesh build for the SDF async task: 1.5s
Async SDF build: 0.6s
Async card rep build: 0.1s
