[Swiftify] Don't drop bounds checks when mixing std::span and counted_by

Browse Source 
When an imported function combines std::span and __counted_by,
std::span would override bounds checks emitted for __counted_by (if it
occurred later in the the parameter list) resulting in no bounds checks
being emitted.
