Summary Same site navigations should keep the same process, even without an opener

Some of the Speculation Rules tests fail, when the navigation whose resource was prefetched ends up in a separate process. Looking into it, it's because the navigation resource is stored in the MemoryCache, which is obviously not shared across different renderer processes. It seems like the easiest way to fix that is to simply avoid these process allocations, which don't necessarily add any security. So we should do that.
