Resolved the issue where the Empty Point support was applied to the histogram, and the trackball was not visible for a value of 0 in the Cartesian Chart in the MAUI Toolkit.

Description of Change

• The IsFillEmptyPoint property has been added to the RangeAreaSeries, SplineRangeAreaSeries, and StackingAreaSeries to prevent the EmptyPointSettings fill from being assigned to the series.
• Changed AND(&&) to OR(||) in UpdateEmptyPointSettings method.
• The overridden ValidateYValues method has been invoked in the BoxAndWhiskerSeries and HistogramSeries to prevent support for empty points.
• The EmptyPointIndexes have been cleared in the OnDataSourceChanged method for the BubbleSeries and ErrorBarSeries to ensure proper functionality during dynamic data collection changes.
• A condition has been added for the trackball to display the 0 value in the RangeColumnSeries and SplineRangeAreaSeries.
• A condition for index bounds has been added in the BubbleSeries, FinancialSeriesBase, RangeSeriesBase, and XYDataSeries.
