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.

    94 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
    95 # $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
    96 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
    97 #
    98 # Of course, Automake must honor this variable whenever it calls a
    99 # tool from the auxiliary directory.  The problem is that $srcdir (and
   100 # therefore $ac_aux_dir as well) can be either absolute or relative,
   101 # depending on how configure is run.  This is pretty annoying, since
   102 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
   103 # source directory, any form will work fine, but in subdirectories a
   104 # relative path needs to be adjusted first.
   105 #
   106 # $ac_aux_dir/missing
   107 #    fails when called from a subdirectory if $ac_aux_dir is relative
   108 # $top_srcdir/$ac_aux_dir/missing
   109 #    fails if $ac_aux_dir is absolute,
   110 #    fails when called from a subdirectory in a VPATH build with
   111 #          a relative $ac_aux_dir
   112 #
   113 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
   114 # are both prefixed by $srcdir.  In an in-source build this is usually
   115 # harmless because $srcdir is `.', but things will broke when you
   116 # start a VPATH build or use an absolute $srcdir.
   117 #
   118 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
   119 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
   120 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
   121 # and then we would define $MISSING as
   122 #   MISSING="\${SHELL} $am_aux_dir/missing"
   123 # This will work as long as MISSING is not called from configure, because
   124 # unfortunately $(top_srcdir) has no meaning in configure.
   125 # However there are other variables, like CC, which are often used in
   126 # configure, and could therefore not use this "fixed" $ac_aux_dir.
   127 #
   128 # Another solution, used here, is to always expand $ac_aux_dir to an
   129 # absolute PATH.  The drawback is that using absolute paths prevent a
   130 # configured tree to be moved without reconfiguration.
