Add infinite iframe-creation test

Browse source 
Location:
https://gorhill.github.io/uBlock/tests/infinite-iframe-creation.html

The test is useful to ensure no runaway memory consumption
in uBO's main process, and is also useful as rough performance
assessment, i.e. we want uBO's main process to be low CPU, etc.

Useful to use with Chromium's Task Manager, which reports both
memory and CPU usage.

Typically to be used with uBO with default settings/lists.
