Compile in support for the Web Audio API on all platforms. It is still
also controlled by a run-time flag.

For the Chromium build, this will currently compile in a stub (no-op)
implementation of the FFTFrame class.

For Google Chrome branded builds, this will now link against Intel's
MKL on Linux and Windows.

Please review. Thanks.

LGTM

Awesome - great to see this!  I guess the trybots will try the stubs version,
but we'll just have to wait and see after landing how the MKL version builds for
Google branded.

Sorry, I tried my best to test this fully before committing. Fixed upstream in
http://trac.webkit.org/changeset/84046 , next WebKit roll will fix the builder.
