loader: Make the Load() function take a process as a regular reference, not a SharedPtr

Browse Source 
A process should never require being reference counted in this
situation. If the handle to a process is freed before this function is
called, it's definitely a bug with our lifetime management, so we can
put the requirement in place for the API that the process must be a
valid instance.
