Fix GH-9589: dl() segfaults when module is already loaded

As of PHP 8.2.0, `zend_module_entry` structures are no longer copied,
so when a module is permanently loaded, and users try to dynamically
load that module again, the structure is corrupted[1], causing a
segfault on shutdown.

We catch that by checking whether any dynamically loaded module is
already loaded, and bailing out in that case without modifying the
`zend_module_entry` structure.
