tests/kernel/smp: Limit 'stress' tests based on factor

Browse source 
SMP tests `inc_concurrency` and `smp_switch_torture` use a 'stressing'
approach to verify their results: run something for some time (or some
number of repetitions). However, in some environments, current 'stress'
levels can be quite high, making tests take a long time - environments
like emulators/simulators.
This patch adds a Kconfig that allows one to define a percentage factor
to the 'stress' (time or repetitions) used by these tests.
