[MIRROR] Wearing Hailer gives unique death SFX [MDB IGNORE] (#24634)

* Wearing Hailer gives unique death SFX (#79216)

## About The Pull Request

If you die with a SecHailer on, a unique sound effect will play (created
entirely by me using in-game files):

https://github.com/tgstation/tgstation/assets/42353186/042e4159-57f3-4cc1-8d96-4dc7289f194b

(Please note that the pitch is randomized)
You can give any mask's unique death sound effects now.
## Why It's Good For The Game
SecHailers can change people's voices. Why not make them sound different
when they die? It could be a humorous reference with a unique sound.
SecHailers' voice changer function is a reference, which I expanded by
also making a unique death sound effect.

Also now you can make more masks with unique death sound effects if you
want to.
## Changelog
