rewrite PgpSignEncrypt data flow

- introduce high-level SignEncryptOperation for uri to uri signing/encryption
- use SignEncryptParcel for high-level operation parameters
- use PgpSignEncryptInput plus streams for low-level operation parameters
- get rid of all sign/encrypt logic in KeychainIntentService
