Add a way to query if a device exists on the wire server

Chromium tracks the devices which live on the wire so it can
automatically call tick on devices that have pending work. This used
to be done by querying an (id, generation) pair and checking if it
resolves to a non-null device.

This CL adds a new way to query directly using the device, since a
refactor in Chrome will change creation such that the id and generation
is not known when a new device is requested.

Also fixes a bug for device callbacks where the required callback
userdata wasn't fully populated for devices created with
requestAdapter. Update a test to check for this as well.
