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