lib/tests: convert test_min_heap module to KUnit

Browse Source 
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.
