Config system event task stack size in different application.
Configure the "main task" stack size. This is the stack of the task
which calls app_main(). If app_main() returns then this task is deleted
and its stack memory is freed.

Configure the IPC tasks stack size. One IPC task runs on each core
(in dual core mode), and allows for cross-core function calls.
See IPC documentation for more details.
The default stack size should be enough for most common use cases.
It can be shrunk if you are sure that you do not use any custom
IPC functionality.
