AdjustImportDataFaceMaterialIndex

(
    const TArray< FSkeletalMaterial >&...,
    TArray< SkeletalMeshImportData::FMa...,
    TArray< SkeletalMeshImportData::FMe...,
    int32 LODIndex
)

Before building skeletalmesh base LOD (LOD index 0) using MeshUtilities.BuildSkeletalMesh, we want to adjust the imported faces material index to point on the correct sk material.
