Multiple issues with Enums

[msonnemans]

1. Enum.lua gets the type of variable TEnum at line 161 but TEnum is already a type if the Enum.TryParse(Type type, ...) methos variant is used. Therefore the exception at line 56 is always thrown.

2. Enum.IsDefined errors with `String.lua:172: bad argument var arr = new[] { 1, 2, 3, 4 };语法的支持 #1 to 'find' (string expected got boolean)

3. If the enum is defined in a different module, all of the above methods don't work anymore because the type parameter is nil.

Example:

            string a = "andre";
            if (Enum.TryParse(typeof(PedModel), a, true, out object b))
                Console.WriteLine((int)b);

With PedModel defined in a different module, it is always nil and the assertions fail.
