Bug 2000885 - create an ai window singleton registered with BrowserComponents.manifest r=ai-frontend-reviewers,pdahiya

instead of https://github.com/Firefox-AI/firefox-prototypes/blob/smart-window/browser/base/content/browser-smart-window.js loaded to every browser window, we can have a singleton manage per-window state and provide helpers like if the feature is enabled bug 2000882 likely also checking browser.ml.enable as a global disable

here's an example of LinkPreview initializing for each window https://searchfox.org/firefox-main/search?q=LinkPreview.init

just a basic skeleton module to start is fine
