Updated Bouncy Castle signer unit tests

- Signature operations are now handled by a single algorithm instance
- All key generation operations except generic EC key generation
  operations are now handled by a single algorithm instance
- Ed25519 and Ed448 key generation have the algorithm set to Ed25519 and
  Ed448 respectively
- For generic EC key generation operations the algorithm is given by the
  corresponding curve (since these could be used for either ECDSA or ECDH)
