CLI: VIP and VR should accurately report options for components

[wxtim]

Problem

The current VIP and VR scripts tell users what atomic scripts would be being called. That is,

cylc vip /loc/myworkflow --workflow-name foo -s='BAZ=42'
...
$ cylc validate /loc/myworkflow
...
$ cylc install /loc/myworkflow
...
$ cylc play foo -s='BAZ=42'

These reports should also include a full list of options relevant to that command, as is effectively done for Cylc Play in https://github.com/cylc/cylc-flow/pull/5377:

That is, when called the output should be

...
$ cylc validate /loc/myworkflow -s='BAZ=42'
...
$ cylc install /loc/myworkflow --workflow-name foo
...
$ cylc play foo -s='BAZ=42'

I did something similar for argparse, easy conversion.

Don't have the time to push this one through ATM.
