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.

    22  * This function takes a clip stack and a query rectangle and it produces a reduced set of

    23  * SkClipStack::Elements that are equivalent to applying the full stack to the rectangle. The clip

    24  * stack generation id that represents the list of elements is returned in resultGenID. The

    25  * initial state of the query rectangle before the first clip element is applied is returned via

    26  * initialState. Optionally, the caller can request a tighter bounds on the clip be returned via

    27  * tighterBounds. If not NULL, tighterBounds will always be contained by queryBounds after return.

    28  * If tighterBounds is specified then it is assumed that the caller will implicitly clip against it.

    29  * If the caller specifies non-NULL for requiresAA then it will indicate whether anti-aliasing is

    30  * required to process any of the elements in the result.

    31  *

    32  * This may become a member function of SkClipStack when its interface is determined to be stable.

    33  * Marked SK_API so that SkLua can call this in a shared library build.
