Add performance.speculations.preloads for speculation measurement

Expose preload measurement data on the Performance object.
This provides a live API that can be queried at any time, not just
during page unload.

The "used" attribute contains a coarsened timestamp indicating when the
resource was used.

The "crossorigin" and "as" attributes contain the relevant attributes
of the fetched resource.
