Remove experimental feature grouped_execution_for_eligibile_table_scans, since this feature could cause query failures where queries exceed the split buffering limit and has not been sufficiently useful in practice. We may choose to add this feature back later in a more robust way.

== RELEASE NOTES ==

General Changes
* Remove experimental feature to perform grouped execution for eligible table scans and its associated configuration property ``experimental.grouped-execution-for-elligible-table-scans`` and session property ``grouped_execution_for_eligible_table_scans``
