Subject: [PATCH] Fix #137768: new FBX importer does not import some animations
 correctly

- FBX "root bone" should become the Armature object itself, and not
  an extra bone (follow same logic as Python importer did).
- "World to armature matrix" was not correct for armatures that are
  parented under some other objects with transforms.
- Parenting imported meshes under an Armature was not taking into
  account that the mesh bind transform might not be the same as the
  current mesh node transform (i.e. was not setting "matrix parent
  inverse" to compensate like the Python importer did).
- The repro file in #137768 also exposed an issue that importing custom
  vertex normals was not working correctly in the new importer, when
  mesh is partially invalid (validation alters the mesh, custom normals
  have to be set afterwards).
