I'm a little worried about naming, this usage of "permanent" is easily confused
with our different usage of "persistent".

I don't know if i this would be a good idea, but maybe instead of expressing
this in terms of "allowing" the usual thing (which is permanent storage), phrase
this in terms of forcing the unusual thing (which is session-only-ness).

EnforceSessionOnlyStorage(...);

So cookies, localstorage, etc are allowed (per other methods here)... but then
forced to be session-only.

Done.

   // Allows the embedder to override the request context based on the URL for
   // certain operations, like cookie access. Returns NULL to indicate the
   // regular request context should be used.
