Hide some navigation timing info when cross-origin redirects are present

When a navigation includes cross-origin redirects, the navigation timing
entry should not include information about redirect timing and internal
network timing, as that may expose cross-origin timing information.

This is already implemented and tested, but has been omitted when
refactoring the navigation timing spec into HTML.

Closes #7104
