Move Xdebug enabling/disabling logic to enable_modules
Refactor PHP enable_modules to support Zend Extensions

Do not use dl() function for testing the shared libraries:
- It can't load Zend Extensions (xdebug, opcache etc.)
- It doesn't handle PHP Extension dependency
- The function has been disabled from some SAPIs in upstream

Add debugging and verbose messages for enable_modules logic:
    DEBUG=true ./php/bin/control restart
