  [flang] Fix -debug crash from VScaleAttrPass (#180234)

This pass splits up the `vscaleRange` pass-option from the
`VScaleAttrPass` into `vscaleMin` and `vscaleMax` respectively, since a
`std::pair<>` cannot be used as a cli-option and crashes when running
`flang -march=rv64gcv -O3 file.f90 -mmlir -debug`.

Since the options can now be set individually I added some error
checking following the semantics described in the langref
https://llvm.org/docs/LangRef.html#function-attributes.

I also added tests since there were none for only this pass before.
