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.

52 * @function:
53 * FT_Stream_OpenLZW
54 *
55 * @description:
56 * Open a new stream to parse LZW-compressed font files. This is
57 * mainly used to support the compressed `*.pcf.Z' fonts that come
58 * with XFree86.
59 *
60 * @input:
61 * stream :: The target embedding stream.
62 *
63 * source :: The source stream.
64 *
65 * @return:
66 * FreeType error code. 0~means success.
67 *
68 * @note:
69 * The source stream must be opened _before_ calling this function.
70 *
71 * Calling the internal function `FT_Stream_Close' on the new stream will
72 * *not* call `FT_Stream_Close' on the source stream. None of the stream
73 * objects will be released to the heap.
74 *
75 * The stream implementation is very basic and resets the decompression
76 * process each time seeking backwards is needed within the stream
77 *
78 * In certain builds of the library, LZW compression recognition is
79 * automatically handled when calling @FT_New_Face or @FT_Open_Face.
80 * This means that if no font driver is capable of handling the raw
81 * compressed file, the library will try to open a LZW stream from it
82 * and re-open the face with it.
83 *
84 * This function may return `FT_Err_Unimplemented_Feature' if your build
85 * of FreeType was not compiled with LZW support.
