Move lib/test_min_heap.c to lib/tests/min_heap_kunit.c and convert it to
use KUnit.
This change switches the ad-hoc test code to standard KUnit test cases.
The test data remains the same, but the verification logic is updated to
use KUNIT_EXPECT_* macros.
Also remove CONFIG_TEST_MIN_HEAP from arch/*/configs/* because it is no
longer used. The new CONFIG_MIN_HEAP_KUNIT_TEST will be automatically
enabled by CONFIG_KUNIT_ALL_TESTS.
The reasons for converting to KUnit are:
1. Standardization:
Switching from ad-hoc printk-based reporting to the standard
KTAP format makes it easier for CI systems to parse and report test
results
2. Better Diagnostics:
Using KUNIT_EXPECT_* macros automatically provides detailed
diagnostics on failure.
3. Tooling Integration:
It allows the test to be managed and executed using standard
KUnit tools.
