Breaking changes

• [pickers] Uniformize customization, replace openPickerIcon prop with the components prop.

<DateTimePicker
  components={{
    LeftArrowIcon: AlarmIcon,
    RightArrowIcon: SnoozeIcon,
+   OpenPickerIcon: ClockIcon,
  }}
- openPickerIcon={<ClockIcon />}

• I have followed (at least) the PR section of the contributing guide.

I think that we should drop the openPickerIcon prop too. It seems to be enough to have it inside the components prop

Let's discuss this customization approach first: #24511 (comment)

It doesn't seem like we need this customization option.

Thanks for the feedback, i will make the changes over the weekend.

I have pushed the PR one step forward. The diff in the first custom date time picker example is interesting:

<DateTimePicker
  components={{
    LeftArrowIcon: AlarmIcon,
    RightArrowIcon: SnoozeIcon,
+   OpenPickerIcon: ClockIcon,
  }}
- openPickerIcon={<ClockIcon />}

This seems more predictable.

We don't need this prop: #24511 (comment)

@eps1lon Ok, fair enough, I have changed the lens/framing, isolating the issues and their solutions.

We are no focusing on a differnt problem, previous review was focused on #24511
