Merge #3543

3543: Parameter inlay hint separate from variable type inlay? #2876 r=matklad a=slyngbaek

Add setting to allow enabling either type inlay hints or parameter
inlay hints or both. Group the the max inlay hint length option
into the object.

- Add a new type for the inlayHint options.
- Add tests to ensure the inlays don't happen on the server side
