Update Substrate Dependency (#566)

* Update `sp-io` dependency

* Rename Trait to Config

* RustFmt

* Bump `sp-io` again

* Use new frame_system weight types in Rialto and Millau runtimes

* Update test Runtimes to use new weight types

* Bump `sp-io` again

* Update to not-the latest first.

* Update benchmarks.

* Another Trai.

* Move new weight types into runtime primitive crates

This allows us to check limits for extrinsics from other parts
of the codebase without pulling in the entire chain runtime.

* Remove leftover comments

* Move new functions to a better location

* Small formatting fixes

* Add actual documentation to new weight config types

* Decrease maximum block weight of Millau chain

* Decreease maximum block length of Millau chain
