Julian Bouzas b80a0975c7 event-dispatcher: Register hooks for defined events in a hash table
Since all the current hooks are defined specifically for a particular event
type, we can register the hooks in a hash table using the event type as key
for faster event hook collection.

Also, hooks that are not specific to a particular event type, like constraints
such as 'event.type=*', will be registered in both the undefined hook list,
and also in all the hash table defined hook lists so they are always evaluated.

Even though 'wp_event_dispatcher_new_hooks_iterator()' can still be used, it is
now marked as deprecated because it is slower. The event hook collection uses
'wp_event_dispatcher_new_hooks_for_event_type_iterator()' now because it is
much faster.

Previously, the more hooks we were registering, the slower WirePlumber would
process events as all hooks needed to be evaluated for all events constantly.
This is not the case anymore with this patch. We can register thousands of
hooks, and if only 1 of those runs for a particular event, only 1 will be
evaluated instead of all of them.
