Add to control Speech rate of Accessibility

- There were codes to set Speed before,
 but it was removed for some reason
https://github.sec.samsung.net/m-romaniuk/setting-accessibility-iot/blob/db42e850e96ed8f4fe85b05de9e290a40a2ad617/SettingAccessibilityGadget/AccessibilityMainMenu.cs#L107-L114

- Applied the similar scenario here again
