Subject: arch/x86,cpu/x86,lib/thread: Remove usage of cpu_info from lib/thread
We only ever start and execute threads on the BSP. By explicitly
checking to see if the CPU is the BSP we can remove the dependency on
cpu_info. With this change we can in theory enable threads in all
stages.
BUG=b:194391185, b:179699789
TEST=Boot guybrush to OS and verify coop multithreading still works
