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.

12 * UCommonData An abstract interface for dealing with ICU Common Data Files.
13 * ICU Common Data Files are a grouping of a number of individual
14 * data items (resources, converters, tables, anything) into a
15 * single file or dll. The combined format includes a table of
16 * contents for locating the individual items by name.
17 *
18 * Two formats for the table of contents are supported, which is
19 * why there is an abstract inteface involved.
20 *
21 * These functions are part of the ICU internal implementation, and
22 * are not inteded to be used directly by applications.
