First in a series of PRs that reduces our use of sp-std with a view to deprecating it. This is just looking at /substrate and moving some of the references from `sp-std` to `core`. These particular changes should be uncontroversial. Where macros are used `::core` should be used to remove any ambiguity. part of https://github.com/paritytech/polkadot-sdk/issues/2101
