jeanPerier 925d347c5a [flang] fix IsSimplyContiguous with expressions (#125708) ...

IsSymplyContiguous was visiting expressions and returning false on
expressions like `x(::2) + y`, which triggered an assert in lowering
when preparing arguments for copy-in/out.

Update it to return false for everything that is not a variable, except
when provided a flag to treat PARAMETER bases as variables. This flags
is required for internal usages in lowering where lowering needs to now
if the read-only memory is being addressed contiguously or not.

Update call lowering to always copy parameter array section into
contiguous writable memory when passing them. The rational here is that
copy-out generated in nested calls using the dummy arguments will cause
a segfault.
