Krzysztof Narkowicz 3da3a205fb 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.
