Message:

General: Correct the fallback logic in apache_mod_loaded().

If the apache_get_modules() function is redeclared to return an empty array, apache_mod_loaded() would assume that no Apache modules are installed and activated, which may not be correct.

This commit improves the logic by using pre-existing phpinfo() fallback to check for loaded modules in that case.

Includes replacing a hardcoded number passed as a flag to phpinfo() with the INFO_MODULES predefined constant for clarity.

Follow-up to [7441], [7508], [29330].

Props engahmeds3ed, audrasjb, Clorith, SergeyBiryukov.
Fixes #56010.
