Introduce accessibility focus highlight feature.

When enabled, this feature draws a highlight around the focused
object on a web page whenever focus changes. This can make it
easier to see what object has keyboard focus, especially since
many pages hide it.

There's also a similar feature on Chrome OS, but it uses a layer
above the entire system. This implementation for Chrome browser
uses a layer on top of a BrowserView.

This is behind a flag for experimentation. It won't be shipped
until UI review is complete.

a flag. Run with --enable-features=AccessibilityFocusHighlight
to try it.
