Adam Langley a9ce0f96e1 crypto/{cipher,tls,internal/cryptohw}: prioritise AES-GCM when hardware support is present. ... Support for ChaCha20-Poly1305 ciphers was recently added to crypto/tls. These ciphers are preferable in software, but they cannot beat hardware support for AES-GCM, if present. This change moves detection for hardware AES-GCM support into cipher/internal/cipherhw so that it can be used from crypto/tls. Then, when AES-GCM hardware is present, the AES-GCM cipher suites are prioritised by default in crypto/tls. (Some servers, such as Google, respect the client's preference between AES-GCM and ChaCha20-Poly1305.) Fixes #17779.
