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.

10 Description: Determining Instance Relationships
12 This test is the same as js1_3/inherit/proto-002, except that it uses
13 the builtin instanceof operator rather than a user-defined function
14 called InstanceOf.
16 This tests Object Hierarchy and Inheritance, as described in the document
17 Object Hierarchy and Inheritance in JavaScript, last modified on 12/18/97

21 This tests the syntax ObjectName.prototype = new PrototypeObject using the
22 Employee example in the document referenced above.
