tests: watchdog: Add new test implementation
New test checks watchdog API if the simpliest test cases work correctly. Each test contains description at the begining of the source file. This implementation replace old SoC-centric implementation. Signed-off-by: Karol Lasończyk <[email protected]>

* @brief TestPurpose: verify Watchdog Timer install/setup/feed can work,
12+
* and reset can be triggered when timeout
13+
* @details
14+
* There are three tests. Each test provide watchdog installation, setup and
15+
* wait for reset. Three variables are placed in noinit section to prevent
16+
* clearing them during board reset.These variables save number of the current
17+
* test case, current test state and value to check if test passed or not.
18+
*
19+
* - Test Steps - test_wdt_no_callback
20+
* -# Get device.
21+
* -# Check if the state was changed and test should be finished.
22+
* -# Set callback to NULL value.
23+
* -# Install watchdog with current configuration.
24+
* -# Setup watchdog with no additions options.
25+
* -# Wait for reset.
26+
* - Expected Results
27+
* -# If reset comes, the same testcase should be executed but state should
28+
* be set to finish value and test should return with success.
29+
*
30+
* - Test Steps - test_wdt_callback_1
31+
* -# Get device.
32+
* -# Check if the state was changed. If so check testvalue if interrupt
33+
* occurred.
34+
* -# Set callback as pointer to wdt_int_cb0.
35+
* -# Install watchdog with current configuration.
36+
* -# Setup watchdog with no additions options.
37+
* -# Wait for reset.
38+
* - Expected Results
39+
* -# If reset comes, the same testcase should be executed but state should be
40+
* set to finish value and test checks if m_testvalue was set in interrupt
41+
* right before reset.
42+
*
43+
* - Test Steps - test_wdt_callback_2
44+
* -# Get device.
45+
* -# Check if the state was changed. If so check testvalue if interrupt
46+
* occurred.
47+
* -# Install two watchdogs: set pointer to wdt_int_cb0 as callback for first
48+
* watchdog and wdt_int_cb1 for second one.
49+
* -# Install watchdog with current configuration.
50+
* -# Setup watchdog with no additions options.
51+
* -# Wait for reset and feed first watchdog.
52+
* - Expected Results
53+
* -# If reset comes, the same testcase should be executed but state should be
54+
* set to finish value and test checks if m_testvalue was set in callback
55+
* of second watchdog right before reset.
