Kernel: Initialize threading and process management earlier

Browse source 
This re-arranges the order of how things are initialized so that we
try to initialize process and thread management earlier. This is
neccessary because a lot of the code uses the Lock class, which really
needs to have a running scheduler in place so that we can properly
preempt.

This also enables us to potentially initialize some things in parallel.
