Use a tagged service iterator for uninstall validators instead of individual lazy proxies

Now we can support tags in YAML parsing it would be good to add support for !service_closure in services.yml as per https://symfony.com/doc/current/service_container/service_closures.html - it is also doable by switching to autowiring but good to have both options and be more like Symfony.

Looking at the code actually I think this should just use #[AutowireIterator] as per https://symfony.com/doc/current/service_container/service_subscribers_lo...

This gives you a collection of services that are lazily instantiated and that you can iterate over, which is exactly what we need in ::validateUninstall().

Still needs work to clean up the now-unused proxy classes but BookUninstallTest passes locally so let's see what happens.

Also wondering why the ModuleInstaller itself is lazy, it's not injected into anything?

edit: it is injected into some forms and the ConfigImporter, but we probably will need it there anyway, not sure it is worth being lazy just for that - doesn't seem like critical path.

OptimizedPhpArrayDumper is not capable of restoring iterators, it just converts them to arrays, and the services within are not lazily instantiated.

OptimizedPhpArrayDumper can now dump and restore lazy service iterators and the unused proxy classes have been deleted.

#2961380: Support IteratorArgument in \Drupal\Component\DependencyInjection\Dumper\OptimizedPhpArrayDumper::dumpValue added IteratorArgument to OptimizedPhpArrayDumper but it turns out the implementation was incomplete as the iterators were no longer lazy and just cast to arrays in the restored container, however this is currently otherwise unused in core so I think it's OK to fix here.

Rebased, also added a test that was added over in #3414208: Add support for tagged_iterator to YamlFileLoader

May need a rebase, but appears to have a unit test failure.

Fixed unit test, thanks @kim.pepper for the fix over in #3414208: Add support for tagged_iterator to YamlFileLoader

Rebased following #3414208: Add support for tagged_iterator to YamlFileLoader

Added BC service for the $uninstallValidators argument to ModuleInstaller, probably should add a test for that, and also add back the addUninstallValidator() method and issue a deprecation as well just in case.

mglaman/phpstan-drupal doesn't like YAML tags, opened https://github.com/mglaman/phpstan-drupal/pull/743

#22 The fix was just tagged by @mglaman in a new release https://github.com/mglaman/phpstan-drupal/releases/tag/1.2.10

#3437778: Bump phpstan/phpstan and mglaman/phpstan-drupal to latest probably needs to land to make this MR work.

PHPStan update landed, updated the baseline to include the new deprecation for the BC layer.

MR appears to need manual rebase again

Rebased on 11.x

Hiding some files.

Idea is nice, code looks fine, tests are green.

The only thing that I wonder about if there's still time to deprecate/remove in 10.3.0/11.0.0 since the BETAs of both are already out.
I _think_ we're too late and need to deprecate/remove in 10.3.1/12.0.0, but am not sure
I know I've seen documentation on this before somewhere, but my search-fu is failing me now.

Putting this on RTBC so core committers can decide on this.

This should be deprecated in 11.1 for 12.0.0 at this point. We're probably going to have to deprecate some things in 10.4 for removal in 12.0.0 too at some point, but there's no new API for contrib to implement here so it should be fine in 11.1 as cleanup without affecting contrib compatibility with both major branches. Just needs versions changed in the deprecation messages so went ahead and made/applied suggestions to the MR.

Thanks @catch.

Since there's not yet a version-tag for 11.1.x in the dropdown (nor Git), I think the correct status for this issue would be postponed and we whack a [11.1.x] in the title to have some kind of visual queue?

@Spokje because there's the 11.0.x branch open, we can commit 11.1.x-specific stuff to 11.x now. Then we'll eventually branch 11.1.x off 11.x when we want to start committing 11.2.x-specific stuff.

@catch: Ah, of course, this eludes me every once in a while. Thanks for explaining.

Moving to correct version.

Committed/pushed to 11.x, thanks!

@deprecated in drupal:11.1.0 and is removed from drupal:11.1.0. Inject

Should this not be removed in 12.0.0?
