…ute and improve `#[AutowireLocator]` (nicolas-grekas, kbond)This PR was merged into the 6.4 branch.Discussion----------[DependencyInjection] Add `#[AutowireIterator]` attribute and improve `#[AutowireLocator]`| Q             | A| ------------- | ---| Branch?       | 6.4| Bug fix?      | no| New feature?  | yes| Deprecations? | no| Tickets       | -| License       | MITThis PR is building on#51392 to add an `#[AutowireIterator]` attribute and improve `#[AutowireLocator]`.The new `#[AutowireIterator]` attribute can be used to describe what `#[AutowireLocator]` can do, except that we get an iterator instead of a container.And  `#[AutowireLocator]` can now be used instead of `#[TaggedLocator]`: `#[AutowireLocator('foo')]` and done.In order to describe that you want a list of services, we cannot use named arguments anymore so we have to pass an array now: `#[AutowireLocator(['foo' => 'F', 'bar' => 'B'])]` should be used instead of `#[AutowireLocator(foo: 'F', bar: 'B')]`.Last but not least, this adds support for nesting `SubscribedService` objects in the list of described services. This provides feature-parity with what we can do when implementing `ServiceSubscriberInterface`.I didn't deprecate `TaggedIterator` nor `TaggedLocator`. We could, but maybe we should wait for 7.1?TODO:- [x] add tests - thanks `@kbond`!~PS: while writing this, I realize that we may merge both tags in one, and let `AutowirePass` decide if it should build a locator or an iterator based on the type of the argument that has the attribute. We'd "just" need to find a name that'd work for that.~Commits-------a87f2e0 [DependencyInjection] Add tests for `AutowireLocator`/`AutowireIterator`78018de [DependencyInjection] Add `#[AutowireIterator]` attribute and improve `#[AutowireLocator]`
