Depsgraph: Report FPS when running with --debug-depsgraph-time

The FPS here is measured based on a timestamp from when depsgraph
was previously evaluated.

Allows to ease investigating performance improvements/regressions
which are not related on animation system but on modifications on
a single frame (such as transforming vertex in edit mode).
