Keccak1600_Squeeze/Absorb Layer (rename)

[manastasova]

Issues:

Resolves Keccak1600_ Layer creation, part of #CryptoAlg-2810

Description of changes:

• Rename Absorb and Squeeze functions since they are Keccak-specific.
• Remove of redefinition of |SHAKExxx_BLOCKSIZE| as |SHAKExxx_RATE|.

This PR introduces the lowest API layer for SHA3 and SHAKE new API design:

• Introduce new Keccak1600 API layer.
  • Keccak1600 layer implements KeccakF1600 Absorb and Squeeze functions; Keccak1600 layer does not manage internal input/output buffers.
• Later FIPS202, SHA3 and SHAKE layers will be introduced on the top Keccak1600 APIs.

Call-outs:

Remove OPENSSL_EXPORT from some SHA3/SHAKE functions.
