  [flang] Select proper library APIs for derived type io. (#66327)

This patch syncs the logic inside `getInputFunc` that selects
the library API and the logic in `createIoRuntimeCallForItem`
that creates the input arguments for the library call.
There were cases where we selected `InputDerivedType` API
and passed only two arguments, and also we selected `InputDescriptor`
and passed three arguments.
It turns out we also were incorrectly selecting `OutputDescriptor`
in `getOutputFunc` (`test4` case in the new LIT test),
which caused runtime issues for output of a derived type
with descriptor components (due to the missing non-type-bound table).
