This change adds a CookieStore method,
GetAllCookiesWithAccessSemanticsAsync, which returns a list of all
cookies in the CookieStore along with a list of the
CookieAccessSemantics for each returned cookie. These lists will be in
the same order, so that each cookie in the returned list of cookies has
the access semantics at the same index in the other list.

This is implemented for CookieMonster only, and other CookieStore
implementations will use the default impl which returns UNKNOWN for
all the cookies. A later CL will additionally expose this method
via the CookieManager interface.
