drivers/tone_alarm and tune_control small improvements/cleanup

- drivers/tone_alarm: move to ModuleBase and purge CDev (/dev/tone_alarm0)
 - drivers/tone_alarm: only run on tune_control publication (or scheduled note) rather than continuously
 - drivers/tone_alarm: use HRT to schedule tone stop (prevents potential disruption)
 - msg/tune_control: add tune_id numbering
 - systemcmds/tune_control: add "error" special case tune_id
 - move all tune_control publication to new uORB::PublicationQueued<>
 - start tone_alarm immediately after board defaults are loaded to fix potential startup issues
 - for SITL (or other boards with no TONE output) print common messages (startup, error, etc)
