Follow-up: Remove old DelayCorrection AEC config

This is a follow-up to r9401, where the configuration DelayCorrection
was replaced by ExtendedFilter.

This change also removes the media constraint
kExperimentalEchoCancellation which was replaced by
kExtendedFilterEchoCancellation in the same CL.

Both settings that are now being removed were kept in the code to avoid
API breakages. In https://codereview.chromium.org/1167343004,
depending code has been updated to avoid breakages.
