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.

| michael@0 | 8 | * This class is used to communicate the particular GrEffect used in a draw to the backend-specific |
| michael@0 | 9 | * effect subclass (e.g. GrGLEffect). It is used to by the backend-specific class to generate a |
| michael@0 | 10 | * cache key for the effect, generate code on a program cache miss, and to upload uniform values to |
| michael@0 | 11 | * the program. |
| michael@0 | 12 | * In addition to the effect, it also communicates any changes between the relationship between |
| michael@0 | 13 | * the view matrix and local coordinate system since the effect was installed in its GrDrawState. |
| michael@0 | 14 | * The typical use case is that sometime after an effect was installed a decision was made to draw |
| michael@0 | 15 | * in device coordinates (i.e. use an identity view-matrix). In such a case the GrDrawEffect's |
| michael@0 | 16 | * coord-change-matrix would be the inverse of the view matrix that was set when the effect was |
| michael@0 | 17 | * installed. |
