Consider merging https://chromium.googlesource.com/chromium/blink/+/2b5b2e5c7a3c26e7f0b17c48137d17f140528b0d

Quite a few cleanups in one:
  - Expose only a StorageArea factory for LocalStorage to core.
  - With the above, only use StorageNamespace instances to manage SessionStorage.
  - Eliminate all the unused methods of StorageNamepace from Blink, especially
    copy() (the last user was DumpRenderTree, which is now gone). Copying session
    storage on window creation is handled on the Chromium side.
  - Use OwnPtrs instead of RefPtrs for managing the lifetime of
    StorageNamespace and StorageArea.

This change also has the advantage of further-reducing the size of PageGroup.
