Subclasses of Maintenance that can function without database access can now override canExecuteWithoutLocalSettings to return true. This is useful for scripts that need to be able to run before or without installing MediaWiki. When no config file is present, the storage backend will be disabled. Any attempt to access the database will result in an error. NOTE: This makes MediaWikiServices::disableBackendServices() more comprehensive, to avoid premature failures during service construction. This change makes it necessary to adjust how the installer manages service overrides. The CLI installer is covered by CI, I tested the web installer manually.
