Title: Add a class to configure or disable the boot chime sound

This commit adds a `osx::global::boot_chime_volume` class that sets the `SystemAudioVolume` NVRAM variable to configure speaker volume at boot time so I can silence that infernal "bong" noise without having to remember to mute my laptop before rebooting it.
