[5.x] Ability to cut/copy/paste replicator sets

[jacksleight]

This PR adds the ability to cut/copy/paste sets between different replicators/pages/tabs:

Notes

• Replicators use a list of set config hashes to decide whether the set being copied is compatible with the target replicator.
• Due to its limitations this does not use the Clipboard API. Instead, within the current page the data is stored in a vue component (for reactivity), and local storage is used to persist it between pages/tabs (session storage isn’t suitable as it doesn’t work between tabs).
• Since local storage has no expiry but you don’t want copied values hanging around forever a unique ID stored in a session cookie is attached to the data, so it can be cleared when a new session is started.
• There's a new $clipboard object that takes care of all the data storage and tracking, this means it should be fairly straightforward to add the same feature to other fieldtypes in the future (if wanted).
• I don't really like the fact that the paste buttons hang around (and have taken the steps above to ensure they don't stay there forever). It wouldn't make sense to clear the data on paste since you might want to paste multiple times. Maybe the paste option shouldn't be a button at all, it could be in the [5.x] Field actions #10352 menu. That would also simplify adding the same feature to other fieldtypes since there's no longer any replicator specific UI.
• If the button does stay it needs a better icon, hopefully there's a good one in the streamline set.

It would be very nice to have this merged 👍
Meanwhile, would it be possible to make an add-on from it?

Same with #10361

Just added the option to cut/copy all sets, now that field actions is merged:

@marcingajda It's not really possible to do this (or #10361) in an addon, at least not without creating a whole custom version of the replicator fieldtype.

@jacksleight I see. Finger crossed for your PR's :)
