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 ECMA Section: 10.1.4 Scope Chain and Identifier Resolution
10 Description:
11 Every execution context has associated with it a scope chain. This is
12 logically a list of objects that are searched when binding an Identifier.
13 When control enters an execution context, the scope chain is created and
14 is populated with an initial set of objects, depending on the type of
15 code. When control leaves the execution context, the scope chain is
16 destroyed.
18 During execution, the scope chain of the execution context is affected
19 only by WithStatement. When execution enters a with block, the object
20 specified in the with statement is added to the front of the scope chain.
21 When execution leaves a with block, whether normally or via a break or
22 continue statement, the object is removed from the scope chain. The object
23 being removed will always be the first object in the scope chain.
25 During execution, the syntactic production PrimaryExpression : Identifier
26 is evaluated using the following algorithm:
28 1. Get the next object in the scope chain. If there isn't one, go to step 5.
29 2. Call the [[HasProperty]] method of Result(l), passing the Identifier as
30 the property.
31 3. If Result(2) is true, return a value of type Reference whose base object
32 is Result(l) and whose property name is the Identifier.
33 4. Go to step 1.
34 5. Return a value of type Reference whose base object is null and whose
35 property name is the Identifier.
36 The result of binding an identifier is always a value of type Reference with
37 its member name component equal to the identifier string.
