Reviewed by Alan Baradlay.

During review of the WebKit feature flags, we discovered that PaginateDuringLayoutEnabled
is not read or written to anywhere in the WebKit engine, and should be removed.

The C API stubs are marked as Deprecated, but left in place to avoid breaking any
existing code still calling the functions.
