Revert of Compute tail time from Biquad coefficients (patchset #7 id:120001 of https://codereview.chromium.org/2862373002/ )

Original issue's description:
> Compute tail time from Biquad coefficients

> we compute the actual tail time from filter coefficients.  Many
> typical filters in applications have a tail time of 10 ms or less.
> This allows biquads and downstream nodes to stop processing much sooner
> than what currently happens, reducing CPU usage and allowing GC to
> collect nodes sooner.
