WebAudio: ConvolverNode.channelCount and channelCountMode

For a ConvolverNode, the channelCount can now be set to 1 or 2. The channelCountMode can be "explicit" or "clamped-max". Previously, a channelCount of 1 was not allowed and neither was a mode of "explicit".

Extends ConvolverNode capabilities slightly to allow developers to choose the desired behavior without having to add a GainNode to do the desired mixing.
