lib/thread: Switch to using CPU_INFO_V2

CPU_INFO_V2 changes the behavior of cpu_info(). There is now only 1
cpu_info struct per cpu. This means that we no longer need to allocate
it at the top of each threads stack.

We can now in theory remove the CONFIG_STACK_SIZE alignment on the
thread stack sizes. We can also in theory use threads in SMM if you are
feeling venturesome.

BUG=b:194391185, b:179699789
TEST=Perform reboot stress test on guybrush with COOP_MULTITASKING
enabled.
