Invoking a static abstract member on the interface type itself is not rejected

[zvmsbackend]

It now passes type checking to invoke a static abstract member on the interface type itself, which leads to a System.BadImageFormatException at runtime as the method body is empty.

Repro steps

type IName =
    static abstract Name : string

IName.Name

Expected behavior

Compiler should emit an error for such nonsensical use of static abstract members.

Actual behavior

An exception System.BadImageFormatException: Bad IL format. is raised.

Known workarounds

Do not write such code.
