[Action] Module hook implementation enhancement

[FlorentTorregrosa]

Hello,

As some hooks can be found in other files than .module using hook_hook_info() (https://git.drupalcode.org/project/drupal/blob/8.8.x/core/lib/Drupal/Core/Extension/module.api.php#L84) or hook_module_implements_alter() in some more fancy cases, do you think the WatchModulesHooksImplementationsActions could be improved to handle those cases?

Also maybe the LoadNewModuleFile will need to be reworked.
