What it does

• adds a tooltip to the problems statusbar when hovering over the item.
• displays No Problems when no problems are present.
• displays the count and type of a problem for each problem stat property when problems are present.

How to test

• verify the problem statusbar item tooltip for a collection of different scenarios:
  • multiple errors, warnings, infos
  • no errors

Code wise :ok
Tested on Ubuntu OK
One comment: Since we don't display the "Hints" on the status bar, should we display the "Hint" with the info, ... on the tooltip ?

I initially simply followed the behavior present in VS Code (which both does not display hints).
I think the addition of hints would be a bit too noisy and the interface ProblemStat would need to be updated and in other places as well if we were to simply display them.
