core/types: add handcrafted and generated rlp encoders

[MariusVanDerWijden]

Opened as a draft for discussion. This PR contains a handwritten decoder for headers and autogenerated decoders for all transaction types.
The gains for a header is around 25%
The gains for a dynamic fee transaction is around 23%
The gains for a full block is around 21%
The gains for a StateAccount is around 28%

One thing I don't like about this, is that we are losing the error messages with this change.
