Source/WebCore:

Removing the old Pointer Lock API as one of the final cleanup
changes for the Update to Fullscreen style locking Spec meta
bug https://bugs.webkit.org/show_bug.cgi?id=84402.

This change primarily removes idl, access in navigator,
one event, and supporting infrastructure in page/PointerLock.

In PointerLockController changes were already noted clearly with
TODOs differentiating old and new api sections.
