`set_validation_data` register weight manually, do not use refund when the pre dispatch is zero. (#7327)

Related https://github.com/paritytech/polkadot-sdk/issues/6772

For an extrinsic, in the post dispatch info, the actual weight is only
used to reclaim unused weight. If the actual weight is more than the pre
dispatch weight, then the extrinsic is using the minimum, e.g., the
weight used registered in pre dispatch.

In parachain-system pallet one call is `set_validation_data`. This call
is returning an actual weight, but the pre-dispatch weight is 0.

This PR fix the disregard of actual weight of `set_validation_data` by
registering it manually.
