Code Review

This pull request replaces several {@macro ...} documentation directives with explicit doc comments and temporary TODO notes across multiple UI components in the cupertino_ui and material_ui packages. A review comment identifies a copy-paste error in packages/material_ui/lib/src/autocomplete.dart where the documentation for textEditingController incorrectly references [RawAutocomplete.focusNode] instead of [RawAutocomplete.textEditingController].

Confirmed with @chunhtai this just needs pending change log files to unblock. The batch release process takes the pending changelog files (one per PR to avoid conflicts) and compiles them together for the final changelog before release. See #12274
