Clean up: Accessibility no longer needs site instance or transforms

Clean up: Accessibility no longer needs site instance or transforms

For a while, BrowserAccessibilityManager needed a way to check whether
two frames were in the same site instance, and transform a frame's
coordinates from frame-relative coordinates to page-relative coordinates
if not.

These APIs are no longer necessary because that information is now
captured in the accessibility tree. See bug for details.

This change just deletes code that's now unused.
