feat(iframe): get run option from parent

[cylon324]

now, it will be possible to add to the iframe

<script data-engine-run-options="fetch-options-from-parent=true" src="./preview.web.js"></script>

or start the iframe with src of ./preview.web.js?fetch-options-from-parent=true
then use installRunOptionsInitMessageHandler on the side of the parent window to have a working iframe env.

It will be used to decouple id generation from iframe dom node creation.

Note: iframe initialization in the engine since we have a tech debt here. We have an initializer directly in codux and we need to move it back to make sense.

@barak007 requested to have a timeout and init rejection in case of fetch-options-from-parent is true but parent window is not responding

[cylon324]

@barak007, after discussing with @plisovyi we can argue that:

• timeout does not contribute to a better user experience. it is the responsibility of the parent to timeout if init is stuck.
• time out reject will interfere with debug breakpoints
  therefore I will remove the timeout part
