Reland "Cut down /crypto and switch what is left of it to boringssl". This removes almost all of the /crypto code, leaving around: - openssl_util - random - secure_hash - sha2 which are used by Mojo. This also switches the impl of secure_hash to secure_hash_openssl backed by openssl (in third_party/boring_ssl), as the default one in secure_hash_default is backed by NSS in /net/third_party/nss (and /net is going away).
