  shared/hci: Avoid redundant BPF filter updates on duplicate events

Skip updating the BPF socket filter in bt_hci_register and
bt_hci_register_subevent when the event/subevent is already
registered, since it is already part of the filter.

Similarly, skip updating the filter in bt_hci_unregister and
bt_hci_unregister_subevent when other handlers for the same
event/subevent still remain in the queue.

This avoids unnecessary setsockopt(SO_ATTACH_FILTER) calls when
multiple handlers are registered for the same event code.

  Log Message:
  -----------
  shared/hci: Debounce SO_ATTACH_FILTER with timeout_add(0)

Coalesce multiple BPF filter updates into a single SO_ATTACH_FILTER
setsockopt call by deferring the update to the next event loop
iteration using timeout_add(0, ...).

When bt_hci_register_event or bt_hci_register_subevent is called
multiple times in succession (e.g. from bt_rap_attach_hci), each call
previously triggered a full filter rebuild and setsockopt. Now,
schedule_evt_filter() simply marks a pending update which fires once
in filter_timeout() after all synchronous registrations complete.
