roll: pigweed pw_bluetooth_sapphire: Disallow re-entrant peer removal in PeerCache

Prevent heap-use-after-free when a PeerCache::add_peer_updated_callback,
set_peer_bonded_callback, or ForEach callback calls
RemoveDisconnectedPeer re-entrantly by tracking callback notification
depth in PeerCache and returning false from RemoveDisconnectedPeer while
callbacks are active.
