Description Matt Woodrow 2023-01-11 11:45:29 PST 
<rdar://100866403>

We're currently copying Font creationData across IPC using shmem (as part of the FragmentedSharedBuffer serialisation), but we then copy it back into local memory.

This adds an extra copy, but also means we can't attribute the memory to the WebContent process that owns the Font.
