Sound effects system Part 1: Assets, Stereo sound

[RanPix]

requires #3367

this is mostly intended to be a base for other people to maybe continue on this

has a bit of renaming and test code, i still have to figure out what we will need

the questions i have for now:

• do we want to be able to change the position of sounds? that would require creating some sort of audio soruce with a handle to a current playing sound which could allow for some cool things like a moving breathing of some scary monster
• how would/should we integrate the sound system with music later?
• in future, do we want to have dynamically changable special effects like pitch, reverb or distortion? so that for example when you break the same block all the time it has some pitch variation to make it less repetative

and i also would want to discuss how the ideal api for that would look like, and maybe what tools do we give to the artists

todo:

• doppler effect - separate pr
• simd sound mixing? - separate pr probably
• playing sounds limit - separate pr
• volume control based on how many of the same sounds are playing at the same time? - separate pr
• find other optimizations
• sound zon files should be able to specify the sound file they are using so we can reuse sounds in some cases? (could also be a separate pr if we need that)
• dont process sounds that are too far / too silent

also for now you can tp to 0 0 0 to hear a testing sound thats constantly playing for stereo

CI failed but I also don't understand if this is supposed to be reviewed?

[RanPix]

i think this is ready for review, just a few things to be done before merging:

• remove testing sound/s
• fix windows sounds going insane

Could you record how it's supposed to sound on Linux?
