With the changes from this PR, the "processing done" / "result valid" signal
valid_ohas to be set (for one cycle) at the same time the processing result / output dataresult_ois valid.Thus, the handshake is easier to understand and easier to implement.
✨ Furthermore, this PR provides a rework of the "CFU proxy logic" allowing an (all-combinatorial) CFU operation to commit much faster: the minimum CPU execution time of a single CFU operation is reduced from 4 clock cycles down to 3 clock cycles.
