perf test: Split monolithic 'util' test suite into sub-tests

Refactor the monolithic 'util' test suite into distinct 'String
replacement' and 'BLAKE2s hash' sub-tests using the struct test_case
framework. This improves test reporting granularity and is used in a
subsequent perf test for JUnit XML test result reporting.
