cc4922b2 - [flang] Remove legacy (non-HLFIR) lowering and related options (#196205)

[flang] Remove legacy (non-HLFIR) lowering and related options (#196205) Drop the user-facing options that selected the legacy non-HLFIR lowering path, the always-true `LowerToHighLevelFIR` lowering option, and the descriptor-discretization debug switch: - `-flang-experimental-hlfir` and `-flang-deprecated-no-hlfir` (flang driver and `-fc1`) - `-hlfir` / `--hlfir` (bbc) - `--use-desc-for-alloc` (bbc, debug) Remove every `if (lowerToHighLevelFIR()) { ... } else { ... }` branch in `lib/Lower/`, keeping the HLFIR side. Delete the now-unused legacy helpers in `Bridge.cpp` (`copyVarFIR`, both `genNoHLFIRPointerAssignment` overloads, the legacy block of `genAssignment`) and the always-empty `createMutableProperties` together with its four dead helpers in `Allocatable.cpp`. Drop the corresponding `alwaysUseBox` parameter from `createMutableBox`. Note: tests were modified in https://github.com/llvm/llvm-project/pull/196137 Assisted-by: AI
