Move to OO hooks now we require 11.x

Ran the OO hook rector and then cleaned up coding standards, removed any LegacyHooks - because we don't support less than D11.1.2 and then tried to group the hooks logically.

Ran a few tests locally.

Let's see how this goes w.r.t CI time, reference point for PHPUnit in HEAD is about 18 minutes - https://git.drupalcode.org/project/experience_builder/-/pipelines/466926...

Looks to have saved about 3 minutes which is not too shabby

I defer to @longwave on this — his involvement in core and core having made this conversion dozens of times now makes him better able to call out things that could cause pain.

👆 Bumping priority because this would be nice.

Running a new pipeline to see how much speed gain remains after 📌 Improve CI pipeline runtime Active .

No notable speed difference anymore, although variability is very high.

Test run duration: 2 min 7 sec

I've seen less than that on HEAD, but it really fluctuates between 1:45 and 3:15. I bet this helps make the test runs more consistent :)

Let's land this now, otherwise this has to keep chasing HEAD.

So this MR was built on top of 0.x as of very recently: d28b6220cdca2cce555060f188c326c9c4bbe267. What has changed in the handful of days since then?

Let's look at all hook implementations:

1. git d d28b6220cdca2cce555060f188c326c9c4bbe267 origin/0.x -- *.module
   

   revealed 🐛 Auto-saved Javascript Components CSS changes do not work with CSS aggregation Active needed to be ported into this MR.

3. git d d28b6220cdca2cce555060f188c326c9c4bbe267 origin/0.x -- *.inc
   

   Nothing! 🥳

All green thanks to 🐛 [pending] In progress Active 😊
