It's excessively complex to worry about leaving these few bits for
extensions. If we need to change things, we can spin a new curve ID in
TLS. We don't need to support two versions during the transition because
a fallback to X25519 is still fine.

Since the underlying operation is deterministic the confirmation hash
isn't needed and SXY didn't use it in their proof.

This change includes support for a variant of [HRSS], a post-quantum KEM
based on NTRU. It includes changes suggested in [SXY]. This is not yet
ready for any deployment: some breaking changes, like removing the
confirmation hash, are still planned.
(CLA for HRSS's assembly code noted in b/119426559.)
