Adjusts the Hindi TimeOfDayFormat to display in a LTR orientation in localizations. (#157998)

Fixes https://github.com/flutter/flutter/issues/156565
This update corrects the `TimeOfDayFormat` mapping for the Hindi language. Previously, the format was incorrectly set to `a_space_h_colon_mm` - (a h:mm), but it should be `h_colon_mm_space_a` - (h:mm a) since Hindi is a LTR language.
