Return early if creating a CanonicalCookie from a CookieCraving fails

Changes in this CL:
 - In addition to creating a CanonicalCookie in ShouldIncludeForRequest,
   create it in CanonicalCookie::Create as well. If that fails, return
   early, which will prevent a session from being created in the first
   place.
 - When creating a CanonicalCookie in ShouldIncludeForRequest, return
   false instead of dereferencing a nullptr in the case where creation
   fails.
 - Add DumpWithoutCrashing logging for both of these early returns.
