Bug 1424663 - vectorized ChaCha20 from HACL* for SSSE3 and ARM NEON, r=ttaubert
Summary:
This adds the vectorized ChaCha20 implementation from HACL* to NSS and replaces the old vectorized code.
Note that this is not used on Android as we currently have no way of testing this for Android or use it on Android for Firefox.
