Cryptid rendering should be disabled whenever a Doodle is displayed.
Currently, this condition is occasionally violated due to caching: we
sometimes receive a cached response that there is no logo, followed
by a fresh indication that actually there is one, but the first will have
triggered cryptid rendering, causing overlapping.

This CL solves this bug by invoking the OnLogoAvailable callback in the
LogoService in the Revalidated case (which corresponds to a confirmation
from the server that no logo is available), and tightening the
conditions in NewTabPageLayout to pick up this new invocation.
