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.

16 * The output color of this effect is a modulation of the input color and a sample from a texture.
17 * It allows explicit specification of the filtering and wrap modes (GrTextureParams). It can use
18 * local coords, positions, or a custom vertex attribute as input texture coords. The input coords
19 * can have a matrix applied in the VS in both the local and position cases but not with a custom
20 * attribute coords at this time. It will add a varying to input interpolate texture coords to the
21 * FS.
