 SWORD1: Implement alternative Windows audio driver behavior

 Implements feature request #15092, bringing the DirectSound driver
 as an option for the game.

 For now this is toggleable by editing scummvm.ini and adding:
 windows_audio_mode=true

 Differences between the DOS and Windows audio drivers:
 * DOS:
    - Apparently uses linear volume curves, as per the AIL/Miles drivers;
    - Music can fade in and out;
    - Fades sound effects in and out at each scene change;
    - Lowers the volume of the music each time a speech line is playing;

 * Windows:
    - Uses DirectSound with volume tables for game volume -> decibel
      volume conversion; the resulting logarithmic curve and slightly
      different volume scaling for sound effects ensures audibly
      different intensities for some sounds;
    - Music can only fade out, not in;
    - Does NOT sound effects in and out at each scene change;
    - Does NOT lower the volume of the music each time a speech line is
 playing;
