Backport of #17125 to 31.0.0.

…es. (apache#17125)

changes:
* filter index processing is now automatically ordered based on estimated 'cost', which is approximated based on how many expected bitmap operations are required to construct the bitmap used for the 'offset'
* cursorAutoArrangeFilters context flag now defaults to true, but can be set to false to disable cost based filter index sorting
@clintropolis clintropolis added this to the 31.0.0 milestone Sep 27, 2024
