Conditionally enable double key logic according to:
private browsing mode or privacy.thirdparty.isolate preference and
implement in GetCookieStringCommon and FindCookie where it counts...
With some reservations of how to convince FindCookie users to test
condition and pass a nullptr when disabling double key logic.

  * SUMMARY: Reassignment to a const is NOT an error per ECMA
  * See http://bugzilla.mozilla.org/show_bug.cgi?id=103602
  *
  * ------- Additional Comment #4 From Brendan Eich 2002-01-10 15:30 -------
  *
  * That's per ECMA (don't blame me, I fought for what Netscape always did:
  * throw an error [could be a catchable exception since 1.3]).
  * Readonly properties, when set by assignment, are not changed, but no error
  * or exception is thrown. The value of the assignment expression is the value
  * of the r.h.s.
  *
  * If you want a *strict* warning, pls change the summary of this bug
  * to say so.
