Cross-Origin Storage (latest build)

Automated build of the cross-origin-storage branch at
13b8c5b, for macOS arm64, Linux x86_64, and Windows
x86_64.

Cross-Origin Storage is enabled by default in this build, so
navigator.crossOriginStorage is available immediately -- no
about:config changes needed. Disable it via about:config
(dom.crossOriginStorage.enabled = false) if needed.
