Annotate patch classes and top-level patch functions with @patch instead of the pseudo-keyword patch. This allows the analyzer to read patch files, and matches the syntax that dart2js uses. The deprecated syntax is still supported, but a warning is printed when detected. BUG= Review URL: https://codereview.chromium.org/2220883004 .
