chore: upgrade deps with new typedefs (ipfs#3550)

Upgrades to new version with types

- Uses default aegir ts config
- Fixes all ts errors
- Fully types core-api in ipfs-core-types package
- Makes ipfs-core implement types from ipfs-core-types package
- Removes duplicate types, ipfs-core-types as single source of type truth
- Reduces use of external APIs by internal components in ipfs-core
- Switches to named exports

BREAKING CHANGE: all core api methods now have types, some method signatures have changed, named exports are now used by the http, grpc and ipfs client modules
