Remove unnecassary parameter "sampleRate" for loadAudioResource().

Parameter "sampleRate" is not required for loadAudioResource().
There is FIXME in AudioBus.cpp in blink
FIXME: the sampleRate parameter is ignored. It should be removed from the API.

It will be consist of 3 steps.
1. Removing "sampleRate" in chrome which is called by blink. (included deprecated method)
https://codereview.chromium.org/195043002/

2. Removing "sampleRate" in blink.
https://codereview.chromium.org/194753005/

3. Removing deprecated method from #1
