feat: Add content script world isolation (#17032)

Browse source 
* Execute content script in isolated world

* Inject script into newly created extension worlds

* Create new content_script_bundle for extension scripts

* Initialize chrome API in content script bundle

* Define Chrome extension isolated world ID range

1 << 20 was chosen as it provides a sufficiently large range of IDs for extensions, but also provides a large enough buffer for any user worlds in [1000, 1 << 20).

Ultimately this range can be changed if any user application raises it as an issue.

* Insert content script CSS into document

This now avoids a script wrapper to inject the style sheet. This closely matches the code used by chromium in `ScriptInjection::InjectCss`.

* Pass extension ID to isolated world via v8 private
