Until now, the `PropelTypeGuesser` could only find columns by their
name.
Example: `created_at` was recognized but `createdAt` wasn't.

This PR adds the ability to match column's phpNames (in a
case-insensitive way).

[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.)
