webcrypto: add AES and HMAC key generation
Use a SymKeyHandle to represent these keys internally. Add generateKey() and
GenerateKeyInternal() to do key generation. Add unit tests for AES key
generation, odd key lengths (non-multiple of 8 bit counts), HMAC key generation,
and HMAC key generation with no length supplied.
