test: add tests to validate cache/mem blocks

To validate cache and memory blocks profiling, this patch prepares
tests to profile dedicated kernels using specified counters, to
compare the profiled results against expected ones, and further
show the test is a fail or pass.  Tests here are focusing on cache
hit/miss, memory fetch/write size.
