[Intl] made RegionBundle merge fallback data if using a country-specific locale

See #8442 and symfony/Icu#2.

Essentially, country data fetches from the Intl component do not currently work when using a locale with a country specifier, e.g. `fr_FR`.  This change forces a merge on the data against the root language locale, thus making country data available for such locales.

[DependencyInjection] fixed a non-detected circular reference in PhpDumper (closes #8425)

This circular reference cannot be detected by the compiler pass as we
don't check for method arguments there.

The Container itself already detects such circular references at runtime.

So this fix is about circular references that are not detected at
compile time, and are not even detected at runtime because the code that
would cause the detection is never run (generated after a return
statement.)

When using YAML or XML, the tags validadity are checked during loading, but when using PHP, that's not possible.
So, the added step in the compilation phase does that nicely.

When registering a private event subscriber/listener, the listener was just ignored.

This PR does two things to fix the problem:

 * the event listener pass is done earlier to get access to the private services
 * when a private service is identified, a proper exception is thrown
