Revert 72259 - Bundle audio spatialization resources for use by the web audio API

This CL caused a lot of browser tests to crash on Windows.
It's possible that the crashes were caused by some bot flakiness
but we need to revert this CL first to diagnose the cause.

BUG=none
TEST=none
(I tested locally on Mac OS X against all of my web audio API demos)
