Problems Panel: Introduce new tree level for grouping by message?

[JacksonKearl]

Similar to #98819, but it'd be nice in large refactorings to have an additional tree grouping level beyond the filename to group by message. For instance, in cases like:

I have a large number of problems with the same title, it'd be nice to be able to collapse groups of problems I'm not interested in and have all of the same "sort" of problem be displayed in a linear format I can easily F8 through.

While the filter operator exists, it's not great for this because I need to manually copy the message into the filter, and F8 does not go by the filtered list, it instead takes me through every error regardless of what is in the Problems view.

Some alternative approaches that might work:

1. Sort the problems in each file by their message rather than line number. If the F8 were to observe this ordering, the problem would be largely solved
2. Allow grouping first by problem, then by file. This would potentially be better in cases where a refactoring introduces one or two errors in 50 different files vs 50 errors in one file.
3. Give an action item to each list entry (either inline or context menu) that performs "filter view to this message", and make F8 work on the filtered list.
