[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
