Windows.Foundation.Metadata.OverloadAttribute generated even when it is already manually specified.

[shmuelie]

Describe the bug When authoring WinRT Components, CsWinRT will automatically generate the Overload attribute for you. If I add my own Overload attribute, I expect CsWinRT to not generate one anymore but it still does.

To Reproduce

1. Author a WinRT Component with overloaded methods.
2. Give one of the overloads the Overload attribute with a custom name.
3. See that the method will have two Overload attributes.

Expected behavior That the method only has the Overload attribute I added.
