* 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
