Static member turns into instance member

[goswinr]

A static member turns into an instance member when defined in an interface:
see REPL

Maybe related, there are a few fixes coming in F# 8.0.400 regarding static abstract https://github.com/dotnet/fsharp/blob/main/docs/release-notes/.FSharp.Compiler.Service/8.0.400.md

@goswinr Static interface members (without implementation) are not supported (yet).
But static interface members with default implementation are already supported.

See #3829 for more details.
