Title: Add ACCEPTS to tests equality with its own type

The method was mostly written by jnthn and suggested on IRC.

This is supposed to fix RT #82308: [TODO] [EASY] Implement signature-signature smartmatch.

I submitted a pull request with tests, too:
https://github.com/perl6/roast/pull/27

It's my first significant patch to Rakudo, and you are absolutely welcome to be critical.
