Add LuaUserData.CreateUserDataOfType.

Converts a Lua value to a desired CLR type and wraps it in a userdata to avoid automatic conversions.
Example: a Lua script needs to pass a List`1 to a CLR method expecting System.Object, MoonSharp gets
in the way by converting the List`1 to a MoonSharp.Interpreter.Table and breaking everything.
Wrapping the value in a userdata preserves the original type during conversions.
