Shiny Updates: Updates on update-core.php

[pento]

Branched from #29820.

There are several improvements that can be made to update-core.php.

Adding inline update support to each of the sections on the page would be a great start, allowing everything to be updated without leaving the page.

Once this is in place, some sort of "Update Everything" button would potentially be a nice addition - it would also lay the groundwork for hiding a lot of the UI. If everything can be updated from one button, do we really need to show update buttons for every plugin and theme?

Finally, (this has been mentioned a few times since the original shiny updates work was done), this page is the ideal place for allowing admins to opt-in to auto updates for major WordPress releases, plugins, and themes.

At the 11 March Dev chat, it was decided to scale back shiny updates to just focus on plugins for 4.2 core themes getting the updates in a future release.

With automatic plugin and theme updating added to 5.5, is this a good time to either close or implement this ticket?
