subxt-core crate (#1466)

* start migrating, broken * first iteration of updating * fmt and clippy * add Composite<u32> decoding via scale value patch * bump scale type gen versions * fix decoding with new scale decode * compiling with changed deps * core utils, condig, client, metadata * core crate compiling * signer crate no once lock * add core to no-std-tests, change imports * broken commit, start pulling everything together in subxt * port more things to subxt * events in core crate, extrinsics sadly much more difficult * almost all examples pass again * dynamic values fix in examples * fix no std issue and fmt * remove unused dependencies * fix lightclient impl * runtime version refactor * formatting and addressing nits * more comments addressed * update wasm example and no-std-signer tests * other nits and error impl on signer errors * fix feature flag * fix runtime version refactor * fix doc links * fix integration tests * fix feature flag gated client state * fix native feature in CI * fix lightclient utils * make imports more lean in subxt-core * integrate changes from subxt-core imports into subxt * other changes in subxt simplify imports more * fix and docs * doc false for cli * fix clippy * remove events block hash in tests * codegen no-std support in generated code * export alloc crate for no-std codegen * fix doc test * implement James comments * remove std traits, use core traits instead * address nits * remove unusued dep in no-std tests * fix Box import in no_std * sp-crypto-hashing instead of sp-core-hashing * bump scale-typegen, add no std codegen tests * fix some things * replace unmaintained derivative with derive_where to remove non-canonical warnings * fmt * remove unused dep * fix deps * update artifacts to fix type ID mismatches * bump to latest scale-typegen --------- Co-authored-by: James Wilson <james@jsdw.me>

+//! This doesn't contain much functionality itself, but is easy to convert to/from an `sp_runtime::MultiSignature`
+//! for instance, to gain functionality without forcing a dependency on Substrate crates here.
