storage,kv: faster intent resolution over a key range

[cockroach-teamcity]

Exalate commented:

cockroachdb/cockroach#66268 --- Release note (performance improvement): Intent resolution for transactions that write many intents such that we track intent ranges, for the purpose of intent resolution, is much faster (potentially 100x) when using the separated lock table. Release justification: Fix for high-severity poor performance in existing functionality, and is a low risk, high benefit change, that potentially improves ranged intent resolution speed by 100x.
