Description

### Describe the bug

The FlowDirection property is not respected by the TimePicker control. Setting FlowDirection="RightToLeft" has no visual effect on the control across any platform.

### Steps to reproduce the bug

1) Run the attached sample [TimePickerRepo.zip](https://github.com/user-attachments/files/20977997/TimePickerRepo.zip).
2) Observe the TimePicker's FlowDirection.

### Expected behavior

TimePicker should layout from RightToLeft direction.

Research direction

Run the attached TimePickerRepo.zip sample with WinUI 3 and Windows App SDK 1.7.3, then confirm that FlowDirection="RightToLeft" has no visual effect. Trace the TimePicker layout behavior and add regression coverage; done means the control visibly lays out right-to-left as expected.
