Removes incorrect pruning in `inline stats` that lacked taking into consideration the fact that groupings can be multi-valued. Fixes elastic#139359 (comment) (grouping by an mv fields can lead to inconsistencies in certain queries) Fixes elastic#139359 Fixes elastic#140757 This also extracts a bunch of tests methods from the huge `LogicalPlanOptimizerTests` and moves them to a new test class - `PruneColumnsTests` which should include most of the tests that have in the spotlight the `PruneColumns` optimization rule. (cherry picked from commit 244538b)
