Declarative plugin management (#2180)

* Declarative plugin management

Allow declaring `plugin` entries in the hyprland configuration.

Plugins will be loaded if an entry is added and unloaded if that entry
is removed.

* Replace pointers with copying in updateconfigPlugins

* Include which plugin was declared twice in error
