[dev.boringcrypto] all: merge commit 9d0819b27c (CL 314609) into dev.boringcrypto

Browse source 
There used to be two BoringCrypto-specific behaviors related to cipher
suites in crypto/tls:

1. in FIPS-only mode, only a restricted set of AES ciphers is allowed

2. NOT in FIPS-only mode, AES would be prioritized over ChaCha20 even if
   AES hardware was not available

The motivation of (2) is unclear, and BoringSSL doesn't have equivalent
logic. This merge drops (2), and keeps (1). Note that the list of
FIPS-only ciphers does not have priority semantics anymore, but the
default logic still sorts them the same way as they used to be.
