Subject: Adjust accessibility_ui for Electron
This tweaks Chrome's Accessibility support at chrome://accessibility
to make it usable from Electron by replacing use of the Profile PrefService
with Electron's own PrefService in ElectronBrowserContext. It also removes
usage of BrowserList and Browser as we subclass related methods and use our
WindowList.
