Pass motion to enable pre-checking on Kusama + Polkadot

Pass motion to enable prechecking.

@bkchr The mentioned go ahead signal: Do you have insights whether this is already honored by all deployed parachains on Polkadot and Kusama?

Prior to this we have to make sure 0.9.30 is rolled on a super majority of validators (the necessary node side changes are contained there).

@slumber how are things looking on Rococo/Westend? Have we enabled yet? - disregard, I just saw the messages. Thanks!

On Rococo, do we need to include Paras::ValidateUnsigned here

polkadot/runtime/rococo/src/lib.rs

Line 1388 in d17ee12

Paras: parachains_paras::{Pallet, Call, Storage, Event, Config} = 56,

as Babe does

polkadot/runtime/rococo/src/lib.rs

Line 1315 in d17ee12

Babe: pallet_babe::{Pallet, Call, Storage, Config, ValidateUnsigned} = 1,

polkadot/runtime/parachains/src/paras/mod.rs

Lines 977 to 978 in d17ee12

	#[pallet::validate_unsigned]
	impl<T: Config> ValidateUnsigned for Pallet<T> {

I am confused, aren't we using the Rococo runtime on Versi? Hence how did this work on Versi if it now fails on Rococo?

Ok, Polkadot and Kusama need this as well. This means we need another runtime upgrade before being able to enable it. Ok, I'll make a PR.

I think this was rolled out quite some time ago. Aka it should be already available on all parachains.
