Bastian Köcher ec6a428ade payment_queryInfo: Make it work with WeightV2 (#12633)
* `payment_queryInfo`: Make it work with `WeighV2`

The runtime api for querying the payment info depends on the `Weight` type and broke for old
runtimes that still use the `WeighV1`. This pull requests fixes this by:

1. Bumping the version of the runtime api.
2. Making the node side code use the correct runtime api function depending on the version of the
runtime api.
3. Make the RPC always return `WeighV1`.

Users of the api should switch to `state_call` and decide based on the version of the runtime api
which `Weight` type is being returned.

* Fix tests

Transaction Payment Pallet

This pallet provides the basic logic needed to pay the absolute minimum amount needed for a transaction to be included. This includes:

  • weight fee: A fee proportional to amount of weight a transaction consumes.
  • length fee: A fee proportional to the encoded length of the transaction.
  • tip: An optional tip. Tip increases the priority of the transaction, giving it a higher chance to be included by the transaction queue.

Additionally, this pallet allows one to configure:

  • The mapping between one unit of weight to one unit of fee via [Config::WeightToFee].
  • A means of updating the fee for the next block, via defining a multiplier, based on the final state of the chain at the end of the previous block. This can be configured via [Config::FeeMultiplierUpdate]
