The lvgl library is configured in some tests to use
the libC malloc to allocate heap. In native_posix this
ends up in the underlying OS heap, which cannot be safely
freed in general when the program finnishes, and
ends up being reported by valgrind as leaked on exit. See
https://github.com/zephyrproject-rtos/zephyr/pull/18471
for a longer discussion.
Instead of trying to fix the leak, let's just accept it
but suppress the errors so it does not confuse other
developers

Added a valgrind error supression file which can be used when
running in the POSIX arch.
So far we are supressing 2 types of errors:
* One very normal in glibc, which will be triggered in the nrf52_bsim
* 2 due to the posix arch prioritizing terminating fast over terminating
cleanly. The posix arch, when posix_core_clean_up() is called, will
pthread_cancel all Zephyr threads. But it will NOT wait for them to
finnish, in case any of them was hung or there is any other problem
which would prevent it. Therefore, depending on the execution, some
times the threads will be still lingering when the main thread exits
Somethign similar applies to posix_soc_clean_up().
These 2 are not errors, but conscious choices => Therefore we
supress them
