valgrind: Add error supression file for POSIX arch 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 Signed-off-by: Alberto Escolar Piedras <alpi@oticon.com>

lvgl: Suppress memory leak errors detected by valgrind 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 Signed-off-by: Alberto Escolar Piedras <alpi@oticon.com>
