Spike/implement CSE element to render web-panels

Description

In order to be able to migrate existing web-panels locations to CSE we need to render existing web-panels just like they used to - and as soon as possible, meaning, before on-load is triggered.
We can then migrate existing web-panels locations to be rendered via CSE while providing the better handling of extensions through CSE for any new extensions being developed for said web-item location.
This will further allow us to migrate these locations to pure CSE locations in the future.

Ensure that existing web-panel HTML that contains script-tags still get executed as expected!
