USD Exporter: removed 'Visible Objects Only' exporter option

The way the USD exporter currently works, it is not possible to export
invisible objects. As such, the 'Visible Objects Only' option was
confusing.

Exporting invisible objects means obtaining invisible evaluated objects
from the depsgraph, which is not something that's currently implemented.
Once that's done, we can reintroduce this option.
