  [flang][OpenMP][Semantics] improve semantic checks for array sections (#132230)

I'm not sure why strides were not allowed in array sections: the stride
is explicitly allowed by the standard from the first version where array
sections were introduced. The limitation is that the stride must not be
negative.

Here I have added the check for a negative stride and updated the test
for a zero length section to take account of the stride.
