kunit: Add example of test suite that can be skipped at runtime

Browse Source 
Add an example test suite name 'example_test_skip_suite' to
'kunit-example-test.c' that shows how to skip an entire test suite based on
runtime conditions.

The example suite 'example_skip_suite' provides a 'suite_init' callback
named example_skip_suite_init() which marks the entire suite as skipped
using kunit_mark_skipped().

This demonstrates a way for conditionally skipping test suites when any
prerequisites for kunit_suite execution are not met. The 'suite_init'
callback can perform any necessary checks and mark the suite as skipped,
preventing all test cases from executing while also indicating why the
suite was skipped.
