Replace 4096 with rendering quantum size

Replace 4096 with rendering quantum size

The code for AudioBufferSourceHandler::renderFromBuffer had a magic,
undocumented literal value of 4096.  Replace this with
AudioUtilities::kRenderQuantumFrames, because it's clear that the
|numberOfFrames| can't be larger than the quantum size (from the call
tree).  The destination bus should also have a maximum length of this
size.
