feat: Enhance date validation logic and add tests for timePrecision i…

…n DatePickerWidget2 (#37218)

## Description
<ins>Problem</ins>

The DatePickerWidget2 component had incomplete date validation logic,
allowing incorrect dates to be selected, and lacked comprehensive
testing for time precision.

<ins>Root cause</ins>

The date validation logic did not accurately account for time precision,
and the testing was limited, making it difficult to ensure the
component's correctness.

<ins>Solution</ins>

This PR enhances the date validation logic in DatePickerWidget2 to
provide better granularity checks based on the timePrecision property,
and adds comprehensive tests to ensure correct date handling across
boundaries for different timePrecision settings. This PR handles...

- Enhanced date validation logic to accurately account for time
precision.
- Comprehensive testing to ensure correct date handling for all possible
input combinations.
