core/core: Move main process creation into Load()

Now that we have dependencies on the initialization order, we can move
the creation of the main process to a more sensible area: where we
actually load in the executable data.

This allows localizing the creation and loading of the process in one
location, making the initialization of the process much nicer to trace.
