feat: flyPad Checklists refactor and adaption to A380X

[frankkopp]

Summary of Changes

This PR brings the flyPad Checklists to the A380X using a slight blend of the A380X paper checklist and A380X ECL lists.

It includes refactoring how checklists are defined using json5 configurations so that multiple aircrafts can be easily defined using a configuration path that can be determined by the aircraft type. The goal is to enable mods to alter these configurations for the users.
It is planned to integrate this with the currently developed unified configuration framework (#8599)

This PR also enhances the data structure of the checklists to allow for checklist lines ("down to the line" and "below the line") and sub checklists as they appear on the A380X ECL. The aim is to reuse these data structures for the ECL once implemented.

The refactoring also impacts the A32NX checklists with little visible changes to the user.

One noticeable change is that automatically checked items are now updated in all checklists not yet completed. Previously these updates were limited to the checklist associated with the current flight phase which was confusing as it then showed completed items as incomplete (or vice versa) in checklists outside the current flight phase without any hint why the status is displayed incorrectly.
