feat(timepicker): allow input to be of type time with its native placeholder support

[rbalet]

Feature Description

Automatically add : like normal <input type="time"> does,
or let user use the type="time" with the input.

Use Case

Actually, we can type anything into the input, so the user may not understand that he has to enter : after the second character.

The way the native time picker works seems more intuitive.
