feat(time picker): added min/max time constraints

[evwilkin]

What: Closes #5853 and closes #6665

This PR:

• adds minTime, maxTime, and invalidMinMaxErrorMessage props which enable restricting the options shown to a user and throwing an error if the user inputs a time outside the constraints.
• adds an example to the time picker showing these new features.
• fixes bug from TimePicker shows invalid on 12hour lowercase delimiter #6665 where custom delimiter is always changed to uppercase upon time selection/entry when is24Hour prop is not present.

In your example, it looks like the max time is not included in the list. Should it be?

[evwilkin]

@nicolethoen it shouldn't be included as it's currently designed, but we could change that. I'm not touching the time options that are created from the stepMinutes other than to remove any that are earlier than the min or greater than the max.

In the example, the stepMinutes defaults to 30 minute intervals and because the maxTime is 17:15 the last time option shown is 17:00 (as the next option, 17:30, is above the maxTime).

@mcarrano would you expect that we should add an additional time option with their max time (or min time) if it doesn't align with one of the existing time options? In my example, where maxTime=17:15, rather than the last option being 17:00 there would be one more that would be 17:15?

No I wouldn't expect this. The user could always enter that from the keyboard. Seems like pretty much an edge case.
