[host][xdc-server] Set host stream connect status.

The xdc device side sends a ctrl msg when a device stream goes on /
offline.

When a client registers that stream id, or currently has registered it,
we will set them as connected / not connected.

Later on we can use this to know when to queue more data from a client
to the xdc device.

TEST= patch in local usb handler changes

fx shell xdc-test -u -f file
out/build-zircon/tools/xdc-test-host -d -f file

Stream id 1 should be connected.
