Remove pre-standard ChaCha20-Poly1305 ciphers (removed)

In 2013, Chrome 31 deployed new TLS cipher suites based on Prof. Dan Bernstein's ChaCha20 and Poly1305 algorithms. This was later standardized, with small tweaks, at the IETF as RFC 7539 and RFC 7905. We shipped the standardized variant early in 2016 with Chrome 49. We are now removing the pre-standard variants.
