Feedback.wrapForTap(() { _setAm(context); }, context),

This PR increases the remaining touch target sizes in the Material Time Picker that weren't handled in #19936. The AM/PM, minute and hour buttons have all be increased to at least 48x48dp. In addition I have added an InkWell to each of them for better user feedback.
