planner: Use/force to apply prefer range scan

[terry1purcell]

What problem does this PR solve?

Issue Number: close #55632

Problem Summary:

What changed and how does it work?

MySQL will increase the cost of a table scan if FORCE INDEX is used in the query. TiDB does not differentiate between USE and FORCE in the query. This enhancement will add a cost penalty to a full table scan if USE or FORCE is used in the query. It will also apply to ANY full table scan in the query, and not only to the table that the USE/FORCE is applied to. This is in response to customer issues where USE/FORCE is specified, but they still see table scans chosen within their query.

If a USE/FORCE is specified against the PRIMARY index, and there are no other predicates (such that the scan is a full table scan of that primary) - this enhancement will increase that table scan cost.

The cost penalty does not apply to a table range scan.
