ZTEST() [1/2]

ZTEST	(	userspace_thread_stack	,
		test_idle_stack
	)

Show that the idle thread stack size is correct.

The idle thread has to occasionally clean up self-exiting threads. Exercise this and show that we didn't overflow, reporting out stack usage.

ZTEST() [2/2]

ZTEST	(	userspace_thread_stack	,
		test_stack_buffer
	)

Test kernel provides user thread read/write access to its own stack memory buffer.

Thread can access its own stack memory buffer and perform read/write operations.

		NULL	,
		thread_setup	,
		ztest_simple_1cpu_before	,
		ztest_simple_1cpu_after	,
