In some places the code was being overly pedantic; e.g., there is no
need to load our own 32-bit descriptors because the loader's are fine
for our purposes. We can defer loading our own segments until 64-bit.
The sequence is re-ordered to faciliate code sharing between the BSP
and APs when SMP is enabled (all BSP-specific operations occur before
the per-CPU initialization).

This is really just to facilitate CPU bootstrap code between
the BSP and the APs, moving the clear operation out of the way.

In the general case, the local APIC can't be treated as a normal device
with a single boot-time initialization - on SMP systems, each CPU must
initialize its own. Hence the initialization proper is separated from
the device-driver initialization, and said initialization is called
from the early startup-assembly code when appropriate.

The 32-bit and 64-bit assembly startup sequences share quite a
bunch of common code, so it's factored out into one file to avoid
repeating ourselves (and potentially falling out of sync).

The linker script was missing symbols that defined the boundaries
of kernel memory segments (_image_rom_end, etc.). These are added
so that core/memmap.c can properly account for those segments.

Elevate the previously 32-bit-only z_x86_prep_c() function to common
code, so both 32-bit and 64-bit arches now enter the kernel this way.
Minor changes to prep_c.c to make it build with the SMP scheduler on.

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.

This maximum is implicit in the kernel support for SMP, e.g.,
kernel/init.c and kernel/smp.c assume CONFIG_MP_NUM_CPUS <= 4.

Stops leaking very long source paths in build directories; makes them
deterministic.
Besides satisfying a CMake requirement, the new empty_file.c provide a
clue that the actual test code is not in the directory of the test case.
See https://github.com/zephyrproject-rtos/hal_nordic/pull/6 and
https://gitlab.kitware.com/cmake/cmake/issues/19475 for more details.

This was a very early test and got bitrotten inside a esp32-only
whitelist. Make it run generically.
SMP must be forced off by the test (it's commonly a platform default).
Add a build-time failure when the configuration is single-CPU, for
clarity.
Filter the test likewise so it runs on all supported systems.
Also, the key argument to the CPU startup function is vestigial and
the test was being too strict by requiring it to be non-zero.
Finally, the qemu command line needs to predicate the "-smp" argument
on CONFIG_MP_NUM_CPUS and not just CONFIG_SMP so we have an extra CPU
to test against.

This test was written very early. Spinlocks are required for SMP
implementation. They couldn't be tested in terms of it, so the test
used the low level MP API instead. But of course that breaks if SMP
is actually working and the CPU is already started.
No need for that now. Just spawn a thread like any other, and filter
the test to run only on SMP systems.
