Deprecate seat idle_wake

Sway has two knobs to control idling:

- seat idle_inhibit: when the seat is active (ie. not idle), this
  extends the active state. When the seat is idle, this is
  ignored.
- seat idle_wake: when the seat is idle, this wakes up the seat.
  When the seat is active, this is ignored.

The motivation for the deprecation is two-fold:

- The concept of "seat idle state" is ill-defined. Each idle-notify-v1
  client will pass a different idle timeout. With the old logic, a
  seat was declared idle if and only if all idle-notify-v1 timeouts have
  expired. However, if only a portion of the timeouts have expired,
  then some clients would wake up, and the rest would stay active.
  This is inconsistent with the definition of idle_inhibit/idle_wake:
  idle_inhibit was used for clients which are waking up.
- It never worked properly with the new idle-notify-v1 protocol
  and no-one noticed. Only the legacy KDE idle protocol is taken
  into account, but that protocol is not used anymore.
