tests: kernel benchmark: Avoid timeout in nrf52_bsim

Browse source 
This test was configuring the system tick period to 1 second.
The test also constantly aligns to system tick boundaries,
in between each test part, which means the test runs for very long
(it is holding for longer than 1 minute just on those waits between
tests alone).
The nrf sys tick driver configures the RTC to produce still
all RTC interrupts at 32KHz intervals, which cause lots of
interrupts which slow down simulation quite bit.
Overall the test could take longer than 30 seconds in the
nrf52_bsim in CI even that this platform simulated time is decoupled
from real time.

=> Add a new config overlay for the nrf52_bsim board so
we configure there a much higher system tick frequency
It does not affect the test in any way more than shortening
the wait periods between in test part.

Also increment the sys tick to twice per second to speed up
the test in other platforms.
