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.

  * Date:    31 July 2002
  * SUMMARY: Testing regexps containing octal escape sequences
  * This is an elaboration of mozilla/js/tests/ecma_2/RegExp/octal-003.js
  *
  * See http://bugzilla.mozilla.org/show_bug.cgi?id=141078
  * for a reference on octal escape sequences in regexps.
  *
  * NOTE:
  * We will use the identities '\011' === '\u0009' === '\x09' === '\t'
  *
  * The first is an octal escape sequence (\(0-3)OO; O an octal digit).
  * See ECMA-262 Edition 2, Section 7.7.4 "String Literals". These were
  * dropped in Edition 3 but we support them for backward compatibility.
  *
  * The second is a Unicode escape sequence (\uHHHH; H a hex digit).
  * Since octal 11 = hex 9, the two escapes define the same character.
  *
  * The third is a hex escape sequence (\xHH; H a hex digit).
  * Since hex 09 = hex 0009, this defines the same character.
  *
  * The fourth is the familiar escape sequence for a horizontal tab,
  * defined in the ECMA spec as having Unicode value \u0009.
