  Log Message:
  -----------
  [flang] Consolidate copy-in/copy-out determination in evaluate framework (#151408)

New implementation of `MayNeedCopy()` is used to consolidate
copy-in/copy-out checks.

`IsAssumedShape()` and `IsAssumedRank()` were simplified and are both
now in `Fortran::semantics` workspace.

`preparePresentUserCallActualArgument()` in lowering was modified to use
`MayNeedCopyInOut()`
