Enhance null handling in switch transformations
- Updated `Issue3421.cs`.
- Updated `MatchLegacySwitchOnStringWithDict` to check for `leaveContainer` and handle null sections accordingly.
- Introduced an overload for `AddNullSection` to accept `ILInstruction` as the body, improving flexibility.
- Modified existing `AddNullSection` to utilize the new overload, allowing for varied body types in `SwitchSection`.
