Full rollout of revamped immersive layout behind A/B test

[frederickobrien]

Rather than getting into a rebase nightmare in #15922 following #16506, this is a clean run at a wider rollout of the new immersive designs.

This pull request:

• Puts the changes behind a 0% test so we can get the changes out the door and test in the real world
• Sends all immersives down the new grid-based system for those who have opted in to the test
• Applies further adjustments and fixes to the new immersive layout, including ripping out now redundant forks and styling for feature versions of the landscape and portrait immersive layouts

Add ?ab-articles-and-publishing-revamped-immersive-layout=enable to the end of a Guardian url to opt in.

Opt in and go to an immersive piece and you should be met with the new look:

Rather than the old one:

We can follow up on this pull request with further adjustments and fixes until we're happy to roll out the change for real. At that point we can delete the old ImmersiveLayout entirely and get a drink to celebrate.
