Kernel: Increase PS2 timeout to 300 ms, load PS2 in separate thread
...
PS/2 seems to hit command timeout sometimes on slow emulation so
increase the timeouts.
Also move PS/2 device initialization to a different thread because
device indentification waits for timeouts.

Kernel: Rewrite ThreadBlocker
...
This gets rid of a very old bug where kernel panics when thread is being
woken up and unblocked at the same time on different cores. This
required adding a new lock to SchedulerQueue::Node and adding a cap to
how many threads a threadblocker can simultaneously block. I don't think
I ever block more than five threads on the same ThreadBlocker so this
should be fine.
