DawnNative: implement Instance::ProcessEvents

Since https://dawn-review.googlesource.com/c/dawn/+/120940, callbacks
will be deferred to be executed in next device.APITick() instead of
immediately.
However, if the device is already destroyed (last ref dropped),
user/wire_server has no chance to call device.APITick() anymore, leading
to the callbacks waiting in queue forever.

This is also possibly the cause of memory leaks in cluserfuzz tests.

This CL attempt to fix it by implementing Instance::ProcessEvents():
In this method, every created device will invoke APITick() even if it is
already lost/externally released.
