feat(pipe): added the Pipe decorator and the pipe property to View

BREAKING CHANGE:
    Instead of configuring pipes via a Pipes object, now you can configure them by providing the pipes property to the View decorator.

    @Pipe({
      name: 'double'
    })
    class DoublePipe {
      transform(value, args) { return value * 2; }
    }

    @View({
      template: '{{ 10 | double}}'
      pipes: [DoublePipe]
    })
    class CustomComponent {}

Closes #3572
