Fix T65798: Incorrect auto-tex space for Curves

There are several aspects to the fix:

- Always calculate bounding box for meshes and curves from dependency
graph evaluation function.

There is a reason why mesh was tagged for geometry update, so can not
be spare here in attempts to avoid calculation.

- Remove texture space evaluation from RNA accessor.

Such data is to be evaluated by a dependency graph.

Don't see a reason to be different here: we never force evaluation of
any kind from RNA.

- Copy bounding box and texture space to original object for active
dependency graph.

This matches object-level bounding box and allows to remove bounding
box evaluation from RNA.
