SF: pass animation presence info to HWC

Sometimes HWC needs to know whether there are animation layers
in composition. E.g., S3D needs to disable when there is screen
shot layer because it cannot correctly compose it as S3D format.
So always pass this kind of info to HWC no matter whether the
disable external animation property is set.
