[BUG] SteamVR does not close VRserver on exit

[bobsdacool]

Describe the bug
SteamVR launches the vrserver process on steam vr launch.

However, after exiting vr (and even when completely ending steam processe) vrserver remains active, consuming ~150Mib of ram, and prevents steamvr from being launched again.

To Reproduce
Steps to reproduce the behavior:

1. Launch steam
2. Use steamlink to connect oculus quest 3 (press ok when prompt indicates issue with install)
3. launch steamvr and connect
4. exit steamvr
5. attempt to launch steamvr
6. steamvr will launch again; however it will return an error 300.
7. To fix, open process manager and kill the vrserver processes
8. launch steamvr again; steamvr now launches again as normal.

Expected behavior
Steamvr should simply kill the vrserver process when steamvr is exited.

vrlink seems to deadlock when destroying its PipeWire audio nodes.
