Add crypto_ia32 plugin

Currently this plugin provies AES CBC optimized code. Encryption code
supports parallel encryption of 4 buffers with different size and key
which improves performance 4x compared to standard serialized aproach.

On Skylake Server measured performance is around 0.71 clocks/byte with
256 buffers with size in range between 7000 and 8000 bytes.
Measured performance includes overhead of processing crypto ops.
