Added support for UsdSkel animation import. This addresses #110076. Added USDSkeletonReader class which imports UsdSkelSkeleton primitives as armatures. Extended USDMeshReader to import UsdSkelBlendShape as shape keys. Extended USDMeshReader to import USD skinning data as as deform groups and an armature modifier on the mesh object. Added USDMeshReader::get_local_usd_xform() to override the transform computation to account for the binding transformation for skinned meshes.
