feat(DatePicker): Add DateTime support to DatePicker OR new DateTimePicker Component

### Feature Description

Greetings,

I wanted to propose a new feature for the existing DatePicker OR to create a new extended component for "DateTimePicker".

I think the popular implementation for this is currently here:
https://github.com/h2qutc/angular-material-components/tree/master/projects/datetime-picker

However, the project has not been maintained and is only supported for <= Angular 16.

The request itself is straightforward, add "Time" support so that the user can select the Hour, Minutes, Seconds in addition to the date.

### Use Case

Many applications have the requirement of the user selecting the full DateTime (Date, Hours, Mins, Secs) vs. just selecting only a basic date.

Start by reviewing the existing DatePicker and compare its behavior with the referenced datetime-picker implementation. Clarify whether DateTime support belongs in DatePicker or a new DateTimePicker component, then define completion as selecting a date plus hours, minutes, and seconds.
