kern/thread: make thread_current migration-safe
This change removes the current thread member from the run queues, and moves
the responsibility of maintaining it to the architecture specific tcb module.
For the x86 architecture, the TCB functions use a per-CPU pointer that can
be read and set in a single instruction, making it interrupt-safe and thus
migration-safe.
