Light up method tupled parameters

Enhance inlay hints for F# code by adding support for methods and named arguments, and simplify hint creation code in InlayHints.fs.

The F# coder loves inlay hints
They help to avoid syntax stints
But methods and args
Were missing some sparks
This pull request adds them in sprints

WHY

Now that we're on a version of FCS that supports the ArgumentLocations member for supporting parameter hints in methods, we should light this up. This currently fails because the new parameter hint reports at the incorrect position, so I need to figure that part out.

• Extend condition for showing parameter hints to methods as well as constructors (link). This is part of the inlay hints feature for F# code in src/FsAutoComplete.Core/InlayHints.fs.

Example of failing test:

Number of actual hints and expected hints don't match. Expected list to have length 1, but length was 2. Seq:
[|{ Position = { Line = 1
                 Character = 61 }
    Label = String "jsonText ="
    Kind = Some Parameter
    TextEdits = None
    Tooltip = None
    PaddingLeft = None
    PaddingRight = Some true
    Data = None }; { Position = { Line = 1
                                  Character = 61 }
                     Label = String "decoder ="
                     Kind = Some Parameter
                     TextEdits = None
                     Tooltip = None
                     PaddingLeft = None
                     PaddingRight = Some true
                     Data = None }|]

There are two things that need to change here:

• the test needs to update to expect 2 hints
• the second hint has an incorrect position/range. I think the VS F# code may have some pointers here, but I think this just needs a bit of debugging.
