The frame elements already had the correct roles assigned, but this was made completely useless because we had a `display: contents` on them, which strips any accessibility role. This was done for layout purpose that we now can do with subgrids, so we update the component's CSS. We also update the markup so copying stacktrace still works as expected. A webconsole test is added to ensure those stactkrace frames can be navigated with the keyboard. Differential Revision: https://phabricator.services.mozilla.com/D190594
