Add a test case of preemptive thread scheduling.
The scheduler will select the highest priority and
waiting longest thread to be the current thread.

Disabling SMP mode for certain tests was a one-release thing, done to
avoid having to triage every test independently (MANY are not
SMP-safe), and with the knowledge that it was probably hiding bugs in
the kernel.
Turn it on pervasively. Tests are treated with a combination of
flagging specific cases as "1cpu" where we have short-running tests
that can be independently run in an otherwise SMP environment, and via
setting CONFIG_MP_NUM_CPUS=1 where that's not possible (which still
runs the full SMP kernel config, but with only one CPU available).

This commit includes tweaks in several tests, so
that the tests can be passing on ARM QEMU targets,
mps2_an385 and mps2_an521 with Qemu 4.x release.

We didn't have any coverage of the system call handlers for
k_wakeup() and k_is_preempt().
Increase RAM requirements due to stack alignment constraints
on MPU platforms when user mode is enabled.
