[flang] Lower logical comparison and logical operations

This handles the lowering of the logical comparison
to `arith.cmpi` operation. The logical operations `.OR.`, `.AND.`
and `.NOT.` are lowered to `arith.ori`, `arith.andi` and `arith.xori`

This patch is part of the upstreaming effort from fir-dev branch.

Depends on D120559
