Deactivate all extensions flag (#2206)

* feat: allow all extension deactivation

* doc: updated comment

* fix: make sure `register_routes` executes after installed extensions are checked

* chore: code format

* fix: do not run migration on deactivated extensions

* fix: make sure the deactivated extension list is loaded in time

* feat: register extension routes if extension never loaded before

* fix: move `load_disabled_extension_list`

* doc: disable by default
