New pipe syntax.

[ykmnkmi]

@Component(
  exports: [DateTime],
  pipes: [LowerCasePipe, UpperCasePipe],
  selector: 'hello-world',
  template: r'<p title="Time: {{$pipe.lowercase(DateTime.now().toString())}}">Hello {{name | uppercase}}!</p>',
)
class HelloWorldComponent {
  String name = 'world';
}

Using both old and new pipe syntax in one expression is not supported.

From CHANGELOG:

The old pipe syntax (expression | pipeName:arg) is removed. Please use the new syntax for pipes ($pipe.pipeName(expression, arg)) instead.

Old expression | pipeName:positional. Current $pipe.pipeName(expression, positional, named: value). New alternative expression | pipeName(positional, named: value).

I'll continue using the analyzer and remove the old expression parser.
