feat(models): Add auto-validation to clearValidators

#491

This adds optional parameters to the `clearValidators` method to support automatic validation after clearing validators.

- The `clearValidators` signature is updated to include `autoValidate`, `updateParent`, and `emitEvent` boolean parameters.
- If `autoValidate` is set to `true`, `updateValueAndValidity()` is called immediately, allowing the control's validity to be recalculated with the specified options for parent updates and event emissions.
