LibWeb+WebContent: Use anonymous files for OOPWV backing stores

Browse source 
To support this, the GUI process and the WebContent service will now
coordinate their backing store bitmaps. Each backing store can be
referred to by a serial ID, and we don't need to keep resending it
as a file descriptor.

We should probably do something similar in WindowServer. :^)
