[ADP-3339] Extract cardano wallet exe from api package (#4707)

This PR is necessary to incorporate the web ui service into the cardano
wallet application without polluting the `api` package even more. In
fact I'm moving all non-API related modules from the `api` package to
the `exe` package.

- [x] Move `Cardano.Wallet.Shelley`,` Cardano.CLI`,
`Cardano.Wallet.Version`, `Cardano.Wallet.Tracers` to a new `exe`
internal lib.
- [x] Rename them so they form the `Cardano.Wallet.Application`
namespace
