test(tc): test for AP/RSS interface for ROTPK
Adding new test for AP/RSS interface for reading ROTPK for
each 3 types of ROTPKs for: CCA, secure, and non-secure firmware.
Enabled by PLATFORM_TEST=rss-rotpk.
Update to print output when AP/RSS interface platform tests
pass to be able to reuse expect script functionality in CI.
