Remove Algo_Registry usage from public key code.

Instead the key types exposes operations like `create_encryption_op`
which will return the relevant operation if the algorithm supports it.

Changes pubkey.h interface, now RNG is passed at init time.
Blinder previous created its own RNG, now it takes it from app.
