Move SocialConnect packages into new repo (out of monorepo)

[arthurgousset]

Context

I propose moving

phone number privacy packages + identity + encrypted backup to all to a new repo. (social connect)

these all depend on each other and depend on some other celo packages but other packages do not depend on them.

This will make releasing social connect easier, make celo sdks releasing simpler, and provide a home base for social connect which will help developers use that project more easily,

Tactics

• moving away from celo tool to build/ deploy combiner
• what does new repo structure look like?
• who does what?
