Fix fr-CA culture time formatting and parsing

[tarekgh]

Fixes #54021

fr-CA culture is using time format pattern like HH 'h' mm 'min' ss 's' which is causing 2 problems:

• First, we usually derive the time separator from the time pattern. That causing us to use h as time separator. So, when formatting any DateTime object using this culture we produce wrong formatted time e.g., 10 h 5 h 50 h. note that h is used to separate the hour, minute, and second parts in the formatted string.
• Second, the formatted time cannot get parsed back when using DateTime.Parse. This is because we cannot recognize the parts like `min' and 's' in the formatted time.

The fix here is we are special casing this culture to explicitly setting the time separator to : which is other French cultures are using. Also, we added some support for this culture in the date/time parser to recognize such formats.
