fix(protocol)!: Export only things we use from connect and buf (#783)

While working on #775, I found that Vite breaks when we try to bundle `@arcjet/protocol` because these buf and connect dependencies export overlapping identifiers and it doesn't know how to detect the correct one. 

Instead, I slimmed these exports to things that we use. I think I found everything between the various projects but marking this as breaking in case others were being used.
