Matthias Hausner e11ca24053 Use metadata annotation @patch for patch classes
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.
