Remove unused FlatShapes And/Or (#14476)

# Description
This removes the need for the `shape_and` and `shape_or` entries in the
themes. We did not color those underlying FlatShapes or operators
differently.

Closes #14372
# User-Facing Changes
Our theme handling currently doesn't reject invalid entries so should
not cause an error. The non-functional nature was already documented.
