Rework Subxt API to support offline and dynamic transactions (#593)

* WIP API changes * debug impls * Get main crate compiling with first round of changes * Some tidy up * Add WithExtrinsicParams, and have SubstrateConfig + PolkadotConfig, not DefaultConfig * move transaction into extrinsic folder * Add runtime updates back to OnlineClient * rework to be 'client first' to fit better with storage + events * add support for events to Client * tidy dupe trait bound * Wire storage into client, but need to remove static reliance * various tidy up and start stripping codegen to remove bits we dont need now * First pass updating calls and constants codegen * WIP storage client updates * First pass migrated runtime storage over to new format * pass over codegen to generate StorageAddresses and throw other stuff out * don't need a Call trait any more * shuffle things around a bit * Various proc_macro fixes to get 'cargo check' working * organise what's exposed from subxt * Get first example working; balance_transfer_with_params * get balance_transfer example compiling * get concurrent_storage_requests.rs example compiling * get fetch_all_accounts example compiling * get a bunch more of the examples compiling * almost get final example working; type mismatch to look into * wee tweaks * move StorageAddress to separate file * pass Defaultable/Iterable info to StorageAddress in codegen * fix storage validation ne, and partial run through example code * Remove static iteration and strip a generic param from everything * fix doc tests in subxt crate * update test utils and start fixing frame tests * fix frame staking tests * fix the rest of the test compile issues, Borrow on storage values * cargo fmt * remove extra logging during tests * Appease clippy and no more need for into_iter on events * cargo fmt * fix dryRun tests by waiting for blocks * wait for blocks instead of sleeping or other test hacks * cargo fmt * Fix doc links * Traitify StorageAddress * remove out-of-date doc comments * optimise decoding storage a little * cleanup tx stuff, trait for TxPayload, remove Err type param and decode at runtime * clippy fixes * fix doc links * fix doc example * constant address trait for consistency * fix a typo and remove EncodeWithMetadata stuff * Put EventDetails behind a proper interface and allow decoding into top level event, too * fix docs * tweak StorageAddress docs * re-export StorageAddress at root for consistency * fix clippy things * Add support for dynamic values * fix double encoding of storage map key after refactor * clippy fix * Fixes and add a dynamic usage example (needs new scale_value release) * bump scale_value version * cargo fmt * Tweak event bits * cargo fmt * Add a test and bump scale-value to 0.4.0 to support this * remove unnecessary vec from dynamic example * Various typo/grammar fixes Co-authored-by: Alexandru Vasile <60601340+lexnv@users.noreply.github.com> * Address PR nits * Undo accidental rename in changelog * Small PR nits/tidyups * fix tests; codegen change against latest substrate * tweak storage address util names * move error decoding to DecodeError and expose * impl some basic traits on the extrinsic param builder Co-authored-by: Alexandru Vasile <60601340+lexnv@users.noreply.github.com>
