fix(platform-server): don't reflect innerHTML property to attibute (#24213) 

Fixes #19278.

innerHTML is conservatively marked as an attribute for security purpose so that it's sanitized when set. However this same mapping is used by the server renderer to decide whether the `innerHTML` property needs to be reflected to the `innerhtml` attribute. The fix is to just skip the property to attribute reflection for `innerHTML`.
