Kernel: Make Threads always have a name

Browse source 
We previously allowed Thread to exist in a state where its m_name was
null, and had to work around that in various places.

This patch removes that possibility and forces those who would create a
thread (or change the name of one) to provide a NonnullOwnPtr<KString>
with the name.
