math/rand/v2: add ChaCha8
This is a replay of CL 516859, after its rollback in CL 543895,
with big-endian systems fixed and the tests disabled on RISC-V
since the compiler is broken there (#64285).
ChaCha8 provides a cryptographically strong generator
alongside PCG, so that people who want stronger randomness
have access to that. On systems with 128-bit vector math
assembly (amd64 and arm64), ChaCha8 runs at about the same
speed as PCG (25% slower on amd64, 2% faster on arm64).
Fixes #64284.
