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.

8 * This class is used to communicate the particular GrEffect used in a draw to the backend-specific
9 * effect subclass (e.g. GrGLEffect). It is used to by the backend-specific class to generate a
10 * cache key for the effect, generate code on a program cache miss, and to upload uniform values to
11 * the program.
12 * In addition to the effect, it also communicates any changes between the relationship between
13 * the view matrix and local coordinate system since the effect was installed in its GrDrawState.
14 * The typical use case is that sometime after an effect was installed a decision was made to draw
15 * in device coordinates (i.e. use an identity view-matrix). In such a case the GrDrawEffect's
16 * coord-change-matrix would be the inverse of the view matrix that was set when the effect was
17 * installed.
