Analyzer for terminating empty types with a semicolon instead of { } [C# 12]

[glen-84]

With C# 12, you can terminate empty types with a semicolon:

Before:

public interface IApplicationAssemblyMarker { }

After:

public interface IApplicationAssemblyMarker;

This is applicable to classes, records, and structs as well.

It looks a lot neater IMO.
