[flang][hlfir] Apply component lower bounds in hlfir.designate codegen

The array component indices in the "path" of a fir.slice are zero based
because FIR does not know about the component lower bounds.
When lowering hlfir.designate to FIR for `array%x(i, j)`, convert `i` and
`j` to zero based indices before generating the fir.slice.
