dsound: use accurate position when getting playposition

This flag is Vista+ only, but gives much better accuracy in
delay calculations

reduce unneccessary millisecond jitter at later stages.

For now fallbacks exist to not upgrade sinks directly
AE: let timestamps from sink delay propagate as far up as possible
