  [ResourceMonitor] Add support of monitoring for iframes created by script.
https://bugs.webkit.org/show_bug.cgi?id=284639
rdar://137691088

Reviewed by Ben Nham.

If the iframe is created runtime, the script URL that creates the element is also the
target of checking the eligibility.

This patch add support for this case by checking the stack trace when iframe is created
and keep the URL of the known source in HTMLIFrameElement object. Then when document of
the frame is created, ResourceMonitor is also checks those URL.
