Upgrade to Polkadot v0.9.42

Description

This is the upgrade from polkadot-v0.9.32 to polkadot-v0.9.42 that brings several breaking changes:

• Babe refactoring: https://github.com/paritytech/substrate/pull/13883
• Balances refactoring: https://github.com/paritytech/substrate/pull/12951
• Offences refactoring.
• DustRemoval type is incompatible with Treasury.

Fixed errors

• TotalIssuance was not initialized correctly, 79d0d42b and 9b94d8fb.

Will need refactoring

• The pallet duniter-account will need to be refactored for a better integration with the new AccountData 13ab4150.
• Some scenarios (like 9d0c7835) are now deprecated due to the refactoring of the pallet balances that adds checks and providers limiting extrinsics usage.
• The providers, consumers, and sufficients counts need some refactoring to be better integrated with the pallet balances own new counts. 007aba57 introduces some workarounds to get the tests passing (with non blocking errors due to the providers count), but an overall spec reviewing and refactoring will be needed.

Changed (dependencies)

• Upgraded Duniter Substrate.
• Upgraded Duniter Subxt.

Changed

• Updated weight files.
• Updated tests with new Subxt API.
• Changed Babe sealing and RPC according to Babe refactoring.
• Updated pallet configurations according to Offences refactoring.
• Updated xtask.

Added

• Added DustHandle to convert the dust from pallet balances and add it to the treasury f357c9ec.

Deprecated

• One pallet balances benchmark needed https://github.com/duniter/substrate/commit/c36ab4f32454318a47777b24b6533c44121fc10b because pallet duniter-account was adding another provider, 007aba57 workaround deprecated this behavior.

To discuss

• Values setting for HoldIdentifier, FreezeIdentifier, MaxHolds, MaxFreezes, and particularly MaxSetIdSessionEntries.

The current state of this big upgrade is:

1. Compilation without error or warning.
2. DustRemoval and Treasury are incompatible with 0.9.42, and this needs to be fixed.
3. Pallet duniter-account will need some refactoring because to pass pallet balances benchmarks, the new flags: ExtraFlags of pallet_balance::AccountData needs to be set either to new or old logic. As ExtraFlags is private and only default to new logic, I implemented this very inelegant workaround for the moment.
4. Pallet balances benchmark failing with 1 == 2 and is the only extrinsic to fail for all pallets.
5. Starting a node using RUST_LOG=runtime=debug RUST_BACKTRACE=1 cargo run -- -lruntime=debug --dev failed with ERROR tokio-runtime-worker sc_service::task_manager: Essential task babe-worker failed. Shutting down service. but RUST_LOG=runtime=debug RUST_BACKTRACE=1 cargo run -- -lruntime=debug --dev --sealing=instant is working fine, so it seems related to Babe.

If @HugoTrentesaux or @tuxmain see something evident that I'm missing for 5 otherwise I will post on the Polkadot Stack Exchange.
