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).

The 14 individual cases that use these four config files are now
passing reliably when SMP is enabled, after the "Mark sleeping threads
suspended" scheduler fix. Turn it back on.

A few more test cases that are measurably unreliable when run in SMP.
For the most part these work most of the time (though the semaphore
one was pretty borderline -- I measured about 25% failures), but are
measurably unstable against the backdrop of known qemu instability.
Something is clearly going on and we need to come back to these to fix
threadsafety issues.

System Power Management is only supported in Tickless Idle mode.
This patch modifies Kconfig dependencies to ensure System Power
Management option selects Tickless Idle one.
Fixes: #11046
Signed-off-by: Piotr Mienkowski <piotr.mienkowski@gmail.com>
Adds changes to enable existing kernel and timer tests and samples to
be used to test the tickless kernel feature.
Updated samples/philosophers and tests/kernel/timer/timer_api apps
Run the tests using following commands
make pristine && make BOARD=<board> CONF_FILE=prj_tickless.conf qemu
Board could be any of the following
qemu_x86
quark_se_c1000_devboard
