Remove dead code related to Web Audio doppler effects

Doppler already has no effect on AudioBufferSourceNodes, as the only
call to setPannerNode was removed in time for M41:
https://codereview.chromium.org/783273002/

PannerHandler::dopplerRate becomes unreachable next, and pulling at the
thread of unreachable things ends up removing quite a lot.

PannerNode's setVelocity is revealed to have no effect at all, although
it remains in the spec. A spec issue was filed:
