std/crypto/chacha20: add round-reduced versions & cleanup internals
See https://eprint.iacr.org/2019/1492.pdf for justification.
8 rounds ChaCha20 provides a 2.5x speedup, and is still believed
to be safe.
Round-reduced versions are actually deployed (ex: Android filesystem
encryption), and thanks to the magic of comptime, it doesn't take much
to support them.
This also makes the ChaCha20 code more consistent with the Salsa20 code,
removing internal functions that were not part of the public API any more.
No breaking changes; the public API remains backwards compatible.
