 Avoid mangled/derived names in GHCi autocomplete (fixes #11328)

 This changes `getRdrNamesInScope` to use field labels rather than
 selector names for fields from modules with `DuplicateRecordFields`
 enabled. Moreover, it filters out derived names (e.g. type
 representation bindings) that shouldn't show up in autocomplete.

 Test Plan: New test ghci/should_run/T11328
