wgengine/magicsock: only cache N most recent endpoints per-Addr
If a node is flapping or otherwise generating lots of STUN endpoints, we can end up caching a ton of useless values and sending them to peers. Instead, let's apply a fixed per-Addr limit of endpoints that we cache, so that we're only sending peers up to the N most recent.
