Convert strategies to and from compare types For each Index AM, provide a mapping between operator strategies and the system-wide generic concept of a comparison type. For example, for btree, BTLessStrategyNumber maps to and from COMPARE_LT. Numerous places in the planner and executor think directly in terms of btree strategy numbers (and a few in terms of hash strategy numbers.) These should be converted over subsequent commits to think in terms of CompareType instead. (This commit doesn't make any use of this API yet.)
