Refactor SliderWebcomponent: Directly invoke _handleInputChange in at…

…tribute change handlers

- Removed the need to dispatch 'blur' events in attribute change handlers for `valueMin` and `valueMax`.
- Directly call `_handleInputChange` method in `_valueMinAttributeChanged` and `_valueMaxAttributeChanged`.
- Implemented type casting to properly handle the event target.
- Retained suppression of attribute change events to prevent infinite loops.
