feat(plugin): NoBlockedUsers

[rushiiMachine]

Rewrite of my own old plugin NoBlockedMessages to support removing blocked users from UI as much as possible.

All features as of now:

• Remove "Blocked Messages" component from non-dm channels
• Ignore messages from gateway & don't update unread states for blocked users
• Hide blocked users from the currently typing list in chat
• Hide blocked authors of referenced messages in replies
• Hide blocked users from chat autocomplete
• Hide blocked users from the members list
