Site Health: Detect an OPcache file cache as an enabled opcode cache#13206itzmekhokan wants to merge 1 commit into

`opcache_get_status()` reports `opcache_enabled` as false when OPcache runs with `opcache.file_cache_only` enabled, even though the file cache is an active opcode cache. `get_test_opcode_cache()` therefore reported "Opcode cache is not enabled" on those configurations. Treat the `file_cache_only` flag in the status array as an enabled opcode cache. The flag is only present when the file cache is the active backend, so shared memory configurations are unaffected. Fixes #65921.

Site Health reports "Opcode cache is not enabled" on servers running OPcache with
opcache.file_cache_onlyturned on, even though a file-based opcode cache is active.get_test_opcode_cache()treatsopcache_get_status()['opcache_enabled']as the only signal, but OPcache sets that flag tofalsein file-cache-only mode and instead exposes afile_cache_onlykey. The patch accepts either signal. That key is present only when the file cache is the active backend, so shared memory configurations are unchanged.The change only widens what counts as enabled, so no configuration that currently passes can start failing.
