TimeDelta factory function migration.

To aid conversions, first removed "using base::TimeDelta;" and converted
TimeDelta to base::TimeDelta in the affected files.  Then converted all
TimeDelta::FromX() and TimeDelta().FromX() (!) into X().

The changes in this CL were all performed by tools; no manual
interventions occurred.
