What is the current behavior?

Issue URL: resolves #25894 resolves #25708

The wheel picker component that datetime uses has a built-in recovery system when value is no longer represented in items. The picker will scroll to the nearest item and update the value.

This was needed by ion-datetime when switching between min or max values such that the selected time become invalid. (i.e. selecting the min date that has a min time of 09:00 even though the previously selected time is 08:00).

This caused multiple render issues and unexpected value updates.

What is the new behavior?

• Moves the adjustment logic out of the picker component and into datetime. Now the value will be adjusted as the state is being updated (whereas the picker was sometimes updating the state immediately after the state was already updated).
  Note: Ultimately, the team would like to move away from this automatic value adjustment and align more closely with the native datetime-local input behavior. However, that is a breaking change so we opted to fixing the existing behavior for now while we can evaluate alternatives.

Does this introduce a breaking change?

• Yes
• No
