2d12d31f - [flang] Propagate contiguous attribute through HLFIR. (#138797)

[flang] Propagate contiguous attribute through HLFIR. (#138797) This change allows marking more designators producing an opaque box with 'contiguous' attribute, e.g. like in test1 case in flang/test/HLFIR/propagate-contiguous-attribute.fir. This would make isSimplyContiguous() return true for such designators allowing merging hlfir.eval_in_mem with hlfir.assign where the LHS is a contiguous array section. Depends on #139003
