kernel: introduce single-threaded kernel
For very constrained systems, like bootloaders.
Only the main thread is available, so a main() function must be
provided. Kernel objects where pending is in play will not behave as
expected, since the main thread cannot pend, it being the only thread in
the system. Usage of objects should be limited to using K_NO_WAIT as the
timeout parameter, effectively polling on the object.
