Clean/Fix remaining cases of props assignments in resgistrable structs def.

We still had a few deprecated assignements of `bpy.props.xxx` to class
members in our API documentation and one of our py tests. Annotations
are to be used now.

Also remove the section about `register_module` utils, this has been
removed in 2.8.

Caused by rBeead6a604602.

Above commit didnt account for different element types being tagged (face

loops.

Now restore to flush from faces if we are in face select mode.
