Subject: [PATCH] Add support for copying diagnostic messages to the clipboard
 (#3489)

This PR adds support for copying diagnostics messages to the clipboard.

This was already working, but we were missing implementations
clipboard-related methods in the `TestPlatform` that were causing the
tests to fail when the copying functionality was added.

Release Notes:

- N/A
