Cross-Origin Storage (latest WebKit build)

Automated build of the cross-origin-storage branch at
c876e28.

navigator.crossOriginStorage is enabled by default in these
builds, so it is available on any secure context with no flags to
set. Each archive contains a run-minibrowser.sh launcher and a
README; on macOS you will need to clear the quarantine flag
(xattr -dr com.apple.quarantine .) because these builds are
unsigned.

These are throwaway builds of an in-development implementation of a
draft WICG proposal, published so the API can be tried without
building WebKit from source. They are not a WebKit release and are
not signed, notarized, or supported.
