dawn_wire: Return early in callbacks after the server is destroyed

Browse Source 
After the server is destroyed, the server's can't do anything like
forward callbacks to the client. Track this with a weak_ptr and
return early if it has expired.

It also updates device destruction in dawn_native so the lost
callback is always called, even on graceful destruction. This
is consistent with the rest of WebGPU where all callbacks are
guaranteed to be called in finite time.
