logging/backend: Make time_origin a class variable instead of a local static

Browse source 
Moves local global state into the Impl class itself and initializes it
at the creation of the instance instead of in the function.

This makes it nicer for weakly-ordered architectures, given the
CreateEntry() class won't need to have atomic loads executed for each
individual call to the CreateEntry class.
