Remove variable shadowing in blink/modules/webaudio

In an effort to reduce or even ban variable shadowing, this renames
a variable to avoid such shadowing. I'm interested in prohibiting
shadowing because I think it might prevent potential jumbo problems.

The exact error this avoids is:
third_party/blink/renderer/modules/webaudio/ error: declaration shadows a local variable [-Werror,-Wshadow]
  for (uint32_t output_bus_index = 0; output_bus_index < output_buses->size();
third_party/blink/renderer/modules/webaudio/ note: previous declaration is here
  uint32_t output_bus_index = 0;
1 error generated.
