[SDK][rocprofv3] MI300 Stochastic PC sampling (#92)

* MI300 Stochastic PC sampling SDK API implementation * ROCProfV3: Stochastic PC sampling Support (#94) * ROCProfV3: MI300 Stochastic PC sampling initial draft * ROCProfV3: Initial Stochastic PC sampling Tests (#95) ROCProfV3: Initial Stochastic PC sampling tests * Update rocprofiler_pc_sampling_record_stochastic_v0_t - update doxygen docs for members - replace rocprofiler_correlation_id_t with rocprofiler_async_correlation_id_t * Relax the check in JSON tests * drain PC sampling buffer during finalize_rocprofv3 * Increase timeout for "Test Install Build" step - 10 minutes -> 20 minutes - "Test Installed Packages" has 20 minutes so "Test Install Build" should also --------- Co-authored-by: Jonathan R.
