[wasm] browser-bench improvements (#59028)

Do not supress all linker warnings. Use UnconditionalSuppressMessage
attribute to supress these we know are ok.

Add new WebSocketTask to the default tasks array.

Enable disabled exception measurements as they don't crash anymore.

Improve summary output.

Example output:
