rename ExecuteFieldSet to ExecuteGroupedFieldSet

this is unfortunately more cumbersome, but more accurate. The grouped field set contains a map of.... field lists (which are also sort of field sets), so this longer name helps considerably with ambiguity.

It may be helpful to later rename CollectRootFields and CollectSubfields to something like BuildRootFieldPlan and BuildSubfieldPlan and the product as FieldPlan, and then the execution step as ExecuteFieldPlan, but that can be done later.
