Refactor ScopeBuilder date picker

[ibelar]

• Create atk-date-picker component wrapper for v-date-picker;

• Allow customizing date picker in the query builder via v-date-picker props.

Example: Starting calendar on a Monday by setting the first-day-of-week option and changing language

    public $datePickerProps = [
        'locale' => 'fr-Fr',
        'masks' => ['input' => 'YYYY-MM-DD'],
        'first-day-of-week' => 2
    ];

What if we set 'masks' => ['input' => 'DD-MM-YYYY'] or phpDateFormat = 'd-m-Y'?
Are these related to that regex and if yes then it will probably fail.

Besides that LGTM.

'masks' => ['input' => 'DD-MM-YYYY'] is for how v-date-picker will display date inside the input to user, while phpDateFormat = 'd-m-Y' is the format that will be set in query. They are are not regex related. This is another reason why I want to switch to flatpickr (see #1467 ) Flatpickr use PHP date format so no need to translate.
