  REGRESSION (Safari 18.2): Allow < 12 byte IV for encrypt

Reviewed by Pascoe.

As part of CryptoKit adoption we did add a limit to the minimum
IV size for AES-GCM encrypt. This change removes that and falls back to the 
CommonCrypto
Implementation if IV is < 12 bytes.

A Test has been added to verify the same.
