feat: implement voice channel status permission and event

[Snipy7374]

Summary

• Closes implement new voice permission and event #1205

I hope this feature doesn't get discarded by discord.

I just read this comment discord/discord-api-docs#6398 (comment) when i almost finished everything 😭, for this reason this PR is not fully complete and untested.

I will not implement discord/discord-api-docs#6400 for now since it could be wasted time. (If they'll ever merge it they're small changes anyways)
