Make HttpDecoder::ParsePriorityFrame() more robust.

1. As https://crbug.com/981291 and https://crbug.com/981646 demonstrate,
   ParsePriorityFrame() used crashes on certain input.  Fix that.
2. Signal QUIC_INVALID_FRAME_DATA instead of QUIC_INTERNAL_ERROR, since
   handling invalid input is not an internal bug but an error on the
   sender's part.
3. Signal error if PRIORITY frame has superfluous payload.
4. Add tests.
