Reorganize crates

[Patrik-Stas]

First incremental shot at #1045

Trying to move what's not currently being worked on / shouldn't cause trouble. Moves:

• aries-vcx-agent under aries/agents/rust
• agency_client, diddoc_legacy, libvcx_core, libvdrtools under aries/legacy
• shared_vcx under aries/shared_vcx
• node wrappers node and vcx-napi-rs under aries/wrappers
• wallet_migrator under tools/

And fixes paths wherever needed

should this readme be moved? https://github.com/hyperledger/aries-vcx/tree/reorg1/agents/rust , and the agents dir deleted?

[mirgee]

I second George's point above; moreover, are there some pending changes to the messages crates or can the be grouped too?

[Patrik-Stas]

@mirgee didn't move messages yet as the did-exchange PR is modifying those
