Add duplicate per-CPU data structures (x86_cpuboot, tss, stacks, etc.)
for up to 4 total CPUs, add code in locore and z_arch_start_cpu().
The test board, qemu_x86_long, now defaults to 2 CPUs.

And set qemu_x86_long board to build with CONFIG_SMP=y by default.
Apparently two benchmark tests - latency_measure and sys_kernel -
do not work with the SMP scheduler, so those tests are disabled.

Add qemu_x86_long board (with CONFIG_X86_LONGMODE=y) for testing.
This requires adding support to soc/ia32 for long mode (trivial),
and adding a quick 64- to 32-bit ELF conversion before invoking
QEMU, which apparently doesn't like 64-bit kernel files.
