What problem does this PR solve?

Issue Number: close #35181, closes #33966, ref #22079

Problem Summary:
In PR #24282 there was an optimization added to remove conditions that was used when calculating the pruned partitions, but it has issues with index-out-of-range and having other side-effects, like index usage is no-longer possible. The optimization is also very limited, since it only removes one selection/comparison (if it would be fixed to work as expected) and could only be used if the partition range is consisting of a single value. So it is better to remove the optimization.

What is changed and how it works?

It's already in release-6.2 branch. https://github.com/pingcap/tidb/commits/release-6.2?before=b3475f2570700ee778530d577cb3b13e38694573+35&branch=release-6.2&qualified_name=refs%2Fheads%2Frelease-6.2

ignore it, I'm diagnosing the problem: why the bot is not auto create cherry-pick pull requests
