[Swiftify] Add MutableSpan support for std::span, and disable it (#80315)

Browse Source 
__counted_by already had MutableSpan support, so add it for std::span
for parity. But since MutableSpan hasn't landed in the standard library
yet, disable emitting it to prevent compilation errors in expansions.
