Update OpenVR from 1.8.19 -> 1.9.16 and remove Sync() calls

Release log:
https://github.com/ValveSoftware/openvr/releases/tag/v1.9.16
```
Removed sync function. Saving of settings is controlled automatically by
the system now. All existing calls to Sync can be deleted. Calls to sync
using old APIs do nothing.
```
