iidx,sdvx: detect SuperstepSound init failures and log a message upon crash (#376)

## Link to GitHub Issue, if one exists
#345 

## Description of change
If we see SuperstepSound failure during boot, remember it, and when the
game eventually crashes, log a series of warning messages to surface why
the game likely failed to launch.

## Testing
Tested both iidx and sdvx with an audio device set to not allow
exclusive mode.
