vo_gpu: d3d11: check for timestamp query support 

Apparently timestamp queries are optional for 10level9 devices. Check
for support when creating the device rather than spamming error messages
during rendering. CreateQuery can be used to check for support by
passing NULL as the final parameter.

See:
