Have UI expose data in VariablePresentationHint

[zobo]

Hi all!

Besides wanting this myself, I get user requests here and there (xdebug/vscode-php-debug#819) to provide visual feedback on whether a field displayed in the Variables pane is private, protected or public. This is all reported within VariablePresentationHint with lots more information. I understand from this old issue #50331 that VS Code doesn't implement this and that adding support similar to VS would be quite an effort (a lot of icon combinations) however how about a simpler approach?

Currently when hovering on a variable name, we get the type name:

Could we just add the other info, if its present? Maybe
(visibility _attributes_ kind) type

Maybe we can call on some of the other DA authors and maintainers to see if they are receiving similar feedback?

Thanks again for all the hard work!

Maybe switch (maybe optionally) to use a rich hover which adds lines/sections for the kind and attributes properties of VariablePresentationHint as well as for visibility.
