test: bench_pktio_sp: add new test for creating pmr rules

Add new test case 'cls_create_pmr', which creates a selected number ('-p')
of PMRs.

bench_tm_func_record() saves now also the number of measurements, which
makes the usage more flexible. Optional precondition check function 'cond'
was added to bench_tm_info_t to enable skipping unsupported tests.
