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 test isn't SMP-safe and won't pass reliably on x86_64 by default
(though it does pass often enough to get CI passes on most things, it
fails spuriously in ways that aren't timing related). Turn off the
second CPU. Fixes#14501

Add k_fifo kernel object usage scenario tests between thread
to thread and thread to ISR.
This test is inspired from test_fifo legacy test from
Zephyr v1.7.0 release.
