Add CHECKs in HostFrameSinkManager
It looks like it's possible for a compromised renderer to get multiple
things to register the same FrameSinkId with HostFrameSinkManager. This
violates assumptions around ownership so turn DCHECKs here into CHECKs.
Also convert DCHECKs into CHECKs for registering/unregistering frame
sink hierarchy just in case.
