Prism was already disallowing arguments after block args, but in parse.y, any comma after a block arg is a syntax error. This moves the error handling into `PM_TOKEN_UAMPERSAND` where we can check if the current type is `PM_TOKEN_COMMA`then raise an error. I've also updated the tests to include the examplesfrom ruby#3112. Fixes: ruby#3112
