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.

9 * SUMMARY: Make our f.caller property match IE's wrt f.apply and f.call
10 * See http://bugzilla.mozilla.org/show_bug.cgi?id=222029
11 *
12 * Below, when gg calls f via |f.call|, we have this call chain:
13 *
14 * calls calls
15 * gg() ---------> Function.prototype.call() ---------> f()
16 *
17 *
18 * The question this bug addresses is, "What should we say |f.caller| is?"
19 *
20 * Before this fix, SpiderMonkey said it was |Function.prototype.call|.
21 * After this fix, SpiderMonkey emulates IE and says |gg| instead.
22 *
