Prior to ~~SERVER-75063~~/~~SERVER-125913~~, planner_access hosted an ad-hoc bounds extractor for clustered index scans. ~~SERVER-125913~~ made this bounds extractor more capable but otherwise continued this pattern.

With ~~SERVER-127890~~/~~SERVER-125911~~ and ~~SERVER-125912~~, collection scans now handle even non-contiguous RecordId ranges, enabling them to re-use the IndexBoundsBuilder. This has several advantages:

reduces code duplication
and the required testing surface
brings clustered collscans to capaility parity wrt. regular index scans (see eg. SERVER-62707)
