tests: boards: intel_adsp: move the smoke test to new ztest API

Migrate the testsuite tests/boards/intel_adsp/smoke to the new
ztest API.

Also splitting them into 2 test suites can be run independently.
But the boot test has a strict order so we changed the name of
the test cases to keep them running in a specified order.
