Adds proper 44.1 support to WebRTC.
This CL removes the existing "WebRTC hack" where the native audio layer runs at 44.1 but WebRTC at 44.0. Now when native WebRTC supports 44100, it is possible to add the same support to WebRTC in Chrome.
BUG=243450
TEST=content_unittests and misc. WebRTC clients using 44.1 as sample rate on input and output devices.
