Add a bind to control backface culling

[mwestphal]

Is your feature request related to a problem? Please describe.
There is a CLI option to control backface culling, but there is no interactive bind to control it yet.
Lets add one.

Describe the solution you'd like

• Create a cycle_backface_type command that cycle between visible, hidden, default in interactor_impl.cxx
• Add an interactive bind for it on Ctrl+B in interactor_impl.cxx
• Add doc and tests

Additional context
See #2404 for an example on how to add an interactive bind
