This PR introduces protection against wasting stateless validator resources on processing state witness when chunk endorsement is guaranteed not to have an effect on the chain state. In particular any chunk with height_created that doesn't exceed the height of the last final block can be safely skipped.

Part of #10565.

LGTM 👍

I wonder if it would be possible to unify this logic and the one for orphaned witnesses, but it might not be that simple 🤔

maybe expand this string to say skipping old state witness generated for already final blocks? (as what "old" witness means may not be clear)

Indeed that would be nice. I've looked into that, but there is very little overlap except for the height check, so not much to extract 😞

fix(minor): more aggressive state witness orphan pool final block hei…
0396473 
…ght check (#11097)

It is safe to also drop state witness with `height_created` equal to the
height of the last final block.
This is mostly to stay consistent with the check introduced in #11081.
