[MIRROR] Adds Blood-drunk and demonic frost miner boss music. [MDB IGNORE] (#23543)

* Adds Blood-drunk and demonic frost miner boss music. (#78123)

Acts as a continuation of PR #77149 for boss music functionality and
implements a BDM and demonic frost miner boss music theme.

More music is good, but I do have some gripes with my own PR. This
particular track relies on instrumentation that when compressed just
doesn't sound as good, and the in-game version is noticeably less
enjoyable that the high quality version. I wish I could help the track
out more, but as is it's already at 811 kb which is barely in line with
file requirements, so i just can't justify bloating the audio file sizes
to make it sound better. You notice this kind of problem a lot with the
higher runtime music and background tracks. It just feels a bit more
clunky than hierophant, but what are you gonna do right?
