[SWDEV-418917] reported that timing skew was being introduced by
roctracer. Most of the cause of this problem seems to stem from outrunning
the double buffering scheme that we use in memory_pool (part of the
reason for this outrun is due to File writing being slow). A semi-quick
fix that may be able to last until RocProf v2 is complete is to allow
adjustment of the buffer size. ROCTRACER_BUFFER_SIZE env variable was
introduced here which allows setting the buffer size of tracer tool.
By increasing the buffer size, an ~8% reduction in execution time when timing
on the program side. This should also reduce the frequency of large delays
when we outrun the buffer. Note: increasing this size dramatically can cause
slow startups (i.e. above 50MB).

When multiple ranks are used, each rank's first logical device always
has GPU ID 0, regardless of which physical device is selected with
CUDA_VISIBLE_DEVICES. Because of this, when merging trace files from
multiple ranks, GPU IDs from different processes may overlap.
The long term solution is to use the KFD's gpu_id which is stable
across APIs and processes. Unfortunately the gpu_id is not yet exposed
by the ROCr, so for now use the driver's node id.

Fix the following error:
roctx.cpp:91:25: error: reinterpret_cast from 'const void *' to 'decltype(report_activity.load())' (aka 'int (*)(activity_domain_t, unsigned int, void *)') casts away qualifiers
report_activity.store(reinterpret_cast<decltype(report_activity.load())>(function),
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
by replacing the 'const void *function' argument with the correct type.

Using a thread_local object is problematic as the thread local
destructors are called first before any global destructor, making
the object invalid while tearing down the process.
rocblas uses a global destructor to clean up the loaded HIP modules
and ends up calling hip_executable_destroy after the timestamp stack
is destructed. As a result the begin timestamp for that API function
is 0.
The solution is to store the phase_enter timestamp in the phase_data.

The timestamps coming from the HIP runtime for asynchronus memory
copies are corrupted (begin > end) because the HSA setting to record
timestamps is turned off by the tracer's HSA intercept.
The solution is to intercept hsa_amd_profiling_async_copy_enable and
remember the application/runtime's request so that it can be ORed with
IsEnabled(ACTIVITY_DOMAIN_HSA_OPS, HSA_OP_ID_COPY).

The tracer tool needs to remember the begin timestamps for API
callbacks, and uses a thread_local std::stack for that purpose.
The issue with thread_local objects is that they are destructed
before anything else when the main thread exits. To work around
that issue, we use a "safe" stack in the roctracer API.
Use the same "safe" stack in the tracer tool.

rocprof errors out with the following message:
symbol lookup 'KernelNameRef' failed: libamdhip64.so.5: undefined \

The HipLoader is incorrectly looking for a KernelNameRef symbol
instead of hipKernelNameRef.
Fixed the typo: KernelNameRef -> hipKernelNameRef.

Starting with gcc-11 (verified with gcc-12 as well), an array
out-of-bounds subscript error is reported for accessing the registration
table element at the operation ID index. Validating the index in the
function calling Register/Unregister does not quiet the warning/error
in release builds, so, for gcc-11 and gcc-12, we disable that warning
just for the RegistrationTable class.

The post-processing script cannot handle HIP ops without a correlation
ID. The correlation ID is needed to connect the record to a HIP stream
and originating thread.
This issue was exposed by a change to the tracer API to report
asynchronous activities even if their originating synchronous API
activity (callback) is not enabled. This was a flow in the API.
Also fix an issue with the API filtering. Undefined API names should
not cause an exception, they should be ignored.

Instead of dlopen'ing RTLD_NOLOAD a library (for example libamdhip64.so)
and rely on the dynamic linker search path, search through the already
loaded shared objects for a library with a matching name.

Remove the hipInitActivityCallback and use the new hipRegister/

The code is easier to read if calling HIPActivityCallbackTracker
enable/disable_check directly. Both enable/disable_check return the
new mask, and the check whether a callback is already installed is
clearer.

The HIP runtime is now allocating the hip_api_data and record on its
stack so we don't need the thread local record_data_pair stack anymore.
Refactor the API callback function to handle both the case where
synchronous user callbacks are requested and the case where asynchronous
records are requested (enable_callback & enable_activity respectively).
If the callback argument (memory pool) is not null, then activity
records are requested.
Remove CorrelationIdRegister and CorrelationIdLookup. These were used
by the HIP runtime to associate a HIP record id to a ROCtracer
correlation id. Instead, the HIP runtime is now using the correlation
ID returned in the hip_api_data_t.
Added a test to check enabling/disabling concurrent callbacks and
activities.
