[Task]: Pipeline construction helper macro about beam

[Kelvinyu1117]

Sure, let me create a document and we can move the discussion on discord.

Let me try to work on this task.
One idea immediately comes to my mind is that we may have different PipelineOption for different Runner for the users in the future, the macro should be able to take the PipelineOption or the individual data members of PipelineOptionas parameters.

Something like this:

#[apache_beam::DirectRunner(DirectRunnerOptions)]
fn main(root: PValue) {
    root.apply(...);
}

@Kelvinyu1117 Thanks!
Since this feature would affect developer experiences so much, could you start from a design doc (that should be listed here) and request reviews in the discord?
