Add missing sounds 1.9.4->1.8

[Beaness]

Adds missing 1.9.4 -> 1.8 sounds, also removes 2 non existing 1.9.4 sound codes
Fixes ViaVersion/ViaRewind#684
Fixes ViaVersion/ViaRewind#501

Made with the help of AI to choose replacement sounds that don't exist on 1.8

I think i've found another reason why some sounds are incorrectly translated on ViaRewind:
ViaBackwards makes sound ids go to the 1.9.0 space at https://github.com/ViaVersion/ViaBackwards/blob/59abf8bd1886cfa3ddf167453e825518496ecd86/common/src/main/java/com/viaversion/viabackwards/protocol/v1_9_1to1_9/Protocol1_9_1To1_9.java#L61
However ViaRewind uses 1.9.4 -> 1.8 mappings https://github.com/ViaVersion/ViaRewind/blob/d73c2198eabb9ada6fa98d6343b7d8cb8b8c05e2/common/src/main/java/com/viaversion/viarewind/protocol/v1_9to1_8/Protocol1_9To1_8.java#L64
for sound translation

Which means every sound >= 415 (item.elytra.flying) gets translated to the wrong sound (off by one)
and explains the following issue: ViaVersion/ViaRewind#682
A more proper fix is probably generating 1.9->1.8 mappings instead and using that in ViaRewind

Latest commit on this PR changes mappings to be 1.9 -> 1.8 so ViaRewind uses the proper identifiers for sounds
