Test kernel supports locating kernel objects without private kernel data anywhere in memory, control access with the memory domain configuration.

For that test kernel object which doesn't contain private kernel data will be used futex. Test performs handshaking between two user threads to test next requirements:

• Place a futex simple_futex in user memory using ZTEST_BMEM
• Show that user threads can write to futex value
• Show that user threads can make wait/wake syscalls on it.
