Description

Adds a feature of the native Android Time Picker to our Material Time Picker. When the user selects an hour, it automatically switches to minute mode.

This is a merging of two pull requests:

• Code changes from @sdolski switching from hours to minutes when selecting or dragging hour #24677
• Tests from @lucaslcode TimePicker moves to minute mode after hour selection #29876

Thanks to both of you for your contributions!
