cpu: Switch off of the CPU's comInstEventQueue.

This switches to letting the ThreadContexts use a thread based/local
comInstEventQueue instead of falling back to the CPU's array. Because
the implementation is no longer shared and it's not given where the
comInstEventQueue (or other implementation) should be accessed, the
default implementation has been removed.

Also, because nobody is using the CPU's array of event queues, those
have been removed.
