Ensure that DisplayListSharedMemoryHeader is never explicitly created or destroyed at compile-time
https://bugs.webkit.org/show_bug.cgi?id=219609
Reviewed by Tim Horton.
Make sure that a `DisplayListSharedMemoryHeader` is never created or destroyed by marking the constructor and
destructor as deleted. A `DisplayListSharedMemoryHeader` should only ever be `reinterpret_cast`-ed from the
first few bytes of a shared display list handle.
