Add keyboard height to WXKeyboardEventData and event handling

The WXKeyboardEventData model now includes a height property to provide the keyboard's pixel height. WXActivity has been updated to calculate and pass this value when posting keyboard events, and the event handler logic has been refactored to always listen for layout changes, improving keyboard visibility and height reporting.
