Fix all providers support

[savpek]

Fix all providers implementation.

Fix one or all issues in document, project and solution scope.

Todo:

• Fixes, tweaks, additional tests etc.
• Using handling seems to require special case, it is very common thing that wanted to be auto fixed so it should be done before initial release.
• Roslynator fixes doesn't work for some reason. Underlaying issue probably affects many custom providers and not only roslynator.
• Fix flaky behavior on fix all issues on document.

Supports:

• Fix one category (by ID) to fix in document, project and solution scope.
• Fix all autofixable issues in document scope.

Document scope

Project scope

Solution scope:

Fix all issues on document when saved at vscode:

The windows test failure has be confused honestly. I clearly works on mac/linux and it fails somewhere deep in the bowles of roslyn.
