arch/x86,lib/thread: Enable thread support in romstage
This change does the following:
* Pushes the cpu_info struct into the top of the stack (just like
c_start.S). This is required so the cpu_info function works correctly.
* Adds the thread.c to the romstage build.
I only enabled this for romstage since I haven't done any tests in other
stages, but in theory it should work for other stages.
BUG=b:179699789
TEST=Boot guybrush with threads enabled in romstage
