UE-17938 Adding ability to set a volume headroom per platform to better achieve platform consistency with respect to volume.

Browse Source 
- Added stubs per platform in their ini file that doesn't change volume, except for mac which this bug is about and for which I reduced the volume by -6 dB. This can be changed by designers as per needed for their game per platform. The final headroom should be set by designers.
- Removed the hard-coded headroom constant used in OpenAL recently added.
