Deprecate AudioListener attributes related to doppler

Deprecate AudioListener attributes related to doppler

The W3C audio group has agreed to remove the doppler effect from
panner nodes. This also means removing the doppler-related attributes
and methods from AudioListener.

See https://github.com/WebAudio/web-audio-api/issues/455

This just deprecates the attributes and methods from the IDL.  The
underlying implementation still has support for this.  We prefer to
remove these all at once when the PannerNode (soon to be deprecated)
is completely removed.

Manually verified the attributes and method cause deprecation warnings.

Please make an entry for this removal in chromestatus.com in order to inform

Of course, deprecation, then removal is much better than sudden removal.

Will do.  

But to do this properly, we will have to revert
https://codereview.chromium.org/783273002/ (which removed the actual doppler
effect) and modify it to fix the race condition.

kbr: PTAL.  

I will revert the doppler removal (that was done previously) in a separate CL.

Even though this has already landed, can you please send an Intent to Deprecate
to blink-dev? I expect no opposition, but some visibility is good.

Done. I'll be adding a chromestatus entry too.
