 Hide derived OccNames from user

 This hides derived OccNames from the Names returned from
 runDeclsWithLocation and clarifies the documentation. This is done to
 ensure that these names (originating from, e.g., derived Generic
 instances and type representation bindings) don't show up in ghci output
 when run with `:set +t`. This fixes #11051.

 Test Plan: Validate with included tests
