  [flang][codegen] Add a conversion for `fir.coordinate_of` - part 2

This patch extends the `FIRToLLVMLowering` pass in Flang by extending
the hook to transform `fir.coordinate_of` into a sequence of LLVM MLIR
instructions (i.e. `CoordinateOpConversion::doRewrite`). The following
case is added:
  3.1 the input object is inside `!fir.ref` (e.g. `!fir.ref<!fir.array>` or
      `!fir.ref<!fir.type>`).
  3.2 the input object is inside `!fir.ptr` (e.g. `!fir.ptr<!fir.array>` or
      `!fir.ptr<!fir.type>`).
>From the point of view of the conversion, 3.1 and 3.2 are currently identical.

This is part of the upstreaming effort from the `fir-dev` branch in [1].
