Port cardano-crypto to cardano-base

## What
Cardano crypto libraries are separated into `cardano-crypto`, used by the wallet and until recently by plutus, and `cardano-base`, used by the node. It would be of interest to unify our crypto libraries into a single repo.

## Why
This would facilitate maintenance and audits.

## External dependencies
We will need to coordinate with the projects using `cardano-crypto` to make the transition

## Acceptance Criteria
All crypto available in `cardano-crypto` is available in `cardano-base`

## Definition of Done
The `cardano-crypto` repo is deleted
