wasm: improve clipboard fallback path
This improves handling of cut/copy/paste clipboard events,
ands allows clipboard access via the common keyboard
shortcuts.
Make the canvas be eligible for clipboard events by
setting the contenteditable attribute. Install clipboard
event handlers directly on the canvas.
Suppress Ctrl+X/C/V key event handling in the keyboard
event handler in order to make the browser generate
clipboard events. Send synthetic key events from the
clipboard event handlers to make the app copy/paste
to Qt’s clipboard at the correct time.
Access the system clipboard data using event.clipboardData.
Task-number: QTBUG-64638
