Part of #7882

Migrate the pallet-transaction-payment to the new pallet attribute macro.

⚠️ Breaking Change ⚠️

From https://crates.parity.io/frame_support/attr.pallet.html#checking-upgrade-guidelines

storages now use PalletInfo for module_prefix instead of the one given to decl_storage: Thus any use of this pallet in construct_runtime! should be careful to update name in order not to break storage or to upgrade storage (moreover for instantiable pallet). If pallet is published, make sure to warn about this breaking change.

So users of the pallet must be careful about the name they used in construct_runtime!. Hence the runtime-migration label, which might not be needed depending on the configuration of the pallet.

cc @shawntabrizi @thiolliere

polkadot and kusama use TransactionPayment as pallet name, thus no need for migration

polkadot companion: paritytech/polkadot#3267

polkadot and kusama use TransactionPayment for pallet name, so no need for migration there.

frame/transaction-payment/src/lib.rs Outdated
pub(super) type StorageVersion<T: Config> = StorageValue<_, Releases, ValueQuery>;

#[pallet::genesis_config]

I removed the generic here as it is not needed

(but also I think we should remove the GenesisConfig completly and remove the Releases storage. If people wonder about which version their pallet is, then they should look at the pallet version stored.
Note that substrate node sand polkadot/kusama nodes don't run this genesis config (it is not configured in construct_runtime).
But we can do in a follow-up PR)

some tests needs fix.

EDIT: I think it is about having proper mock environment in some tests.

Mostly syntax changes; if it compiles, it works.
