This switches AURA to use CurrentSlot instead of LastTimestamp.

Based on: #8020 (so only the last commit is important at the moment)

This switches AURA to use `CurrentSlot` instead of `LastTimestamp`.

As discussed on Element we should be able to remove the slot number inherent data (we are reading it from predigest anyway).

Added runtimenoteworthy label. Any chain using Aura that does a runtime upgrade with this will need to include the RemoveLastTimestamp migration.

Do you mind adding a comment here saying that this can be removed in the future (maybe with a link to this PR)?

Runtimes need to remove the inherent for the module.

Missing this one: https://github.com/paritytech/substrate/blob/master/frame/aura/src/mock.rs#L43

LGTM,

I'm also happy to see those ProvideInherent implementation which just check some other pallet calls removed, the logic is more simple now, IMO.
