To avoid spurious diagnostics about unavailable operations when checking uses of functions that take result builder closures, lookup of result builder operations needs to ignore the restrictions of the `MemberImportVisibility` feature. The result builder transform should simply use the operations that are found and allow later checks to diagnose the use of inaccessible builder operations. Resolves rdar://144100445.
