statistics, planner: make the content in HistColl.ColID2IdxIDs stable

[time-and-fate]

What problem does this PR solve?

Issue Number: close #38457

What is changed and how it works?

1. Make HistColl.ColID2IdxID contains all possible indexes in a stable order.
2. Prefer column stats over index stats in expBackoffEstimation
3. Do not recursively call GetRowCountByIndexRanges in expBackoffEstimation if we are handling a single-column range. This change avoids infinite recursion after changes in 1.
