Merge #43227 #43316 #43563

43227: roachpb: remove PushTxnRequest.InclusivePushTo r=nvanbenschoten a=nvanbenschoten

This completes the migration started in #35297, which was partially finalized in #38446.

Release note: None

43316: storagebase: take RangeDesc by reference in ContainsKey(Range) r=nvanbenschoten a=nvanbenschoten

All callers of this had a *RangeDescriptor, so there's no reason to pass in a large RangeDescriptor struct.

Release note: None

43563: storage/intentresolver: don't capture loop iteration vars in async task r=nvanbenschoten a=nvanbenschoten

It's unclear if we've ever seen issues from this, but I intend to backport the
fix to v19.2, v19.1, and v2.1. I believe the worst thing that could have
happened is that a batch that observed multiple intents or pushed multiple txns
would only end up cleaning up a single one of these. It would then run into some
of these intents again when it tried to re-evaluate, forcing it to push again.
This subverts the parallelism that we were trying to achieve here, but would
never cause a stall.

Release note (bug fix): Ensure that all intents or transactions that a
batch observes are asynchronously cleaned up.
