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  * Version strings are dot-separated sequences of version-parts.

    10  *

    11  * A version-part consists of up to four parts, all of which are optional:

    12  *

    13  * <number-a><string-b><number-c><string-d (everything else)>

    14  *

    15  * A version-part may also consist of a single asterisk "*" which indicates

    16  * "infinity".

    17  *

    18  * Numbers are base-10, and are zero if left out.

    19  * Strings are compared bytewise.

    20  *

    21  * For additional backwards compatibility, if "string-b" is "+" then

    22  * "number-a" is incremented by 1 and "string-b" becomes "pre".

    23  *

    24  * 1.0pre1

    25  * < 1.0pre2

    26  *   < 1.0 == 1.0.0 == 1.0.0.0

    27  *     < 1.1pre == 1.1pre0 == 1.0+

    28  *       < 1.1pre1a

    29  *         < 1.1pre1

    30  *           < 1.1pre10a

    31  *             < 1.1pre10

    32  *

    33  * Although not required by this interface, it is recommended that

    34  * numbers remain within the limits of a signed char, i.e. -127 to 128.
