Welton, Benjamin 2c4e20b951 [SWDEV-516561][1/2] Add MARKER_RANGE_EXTENT to capture ROCTX ranges (#363) 
* [SWDEV-516561][1/2] Add MARKER_RANGE_EXTENT to capture ROCTX ranges

Range extent to capture all work between roctxpush/pop operations. Entry callback takes place during roxtxpush and exit callback takes place in roctxpop. This is primarily to allow us to keep an ancestor id on the ancestor stack such that all operations that take place within the push/pop context can be annotated as being apart of this range. With the current setup (where push and pop are two separate operations that need to be combined externally), we cannot keep an ancestor id on the stack and thus cannot tie tracing events to particular ranges.

Correlation id information is inherited from the push operation. Ancestor id needs to be added in a future commit that also outputs this ancestor to CSV.

Output:

```
[ctest] {'size': 64, 'kind': 7, 'operation': 1, 'correlation_id': {'internal': 1525, 'external': 0, 'ancestor': 1524}, 'start_timestamp': 2932551479402642, 'end_timestamp': 2932551491178449, 'thread_id': 3254861}
[ctest] {'size': 64, 'kind': 8, 'operation': 2, 'correlation_id': {'internal': 1525, 'external': 0, 'ancestor': 1524}, 'start_timestamp': 2932551479405878, 'end_timestamp': 2932551491181214, 'thread_id': 3254861}
```

Note: Kind 8 = range extent op.

* Merge fix

Revert several changes

source/lib/rocprofiler-sdk/marker/range_marker.*

- separate out range marker implementation for standard marker implementation

Update public API with marker core range

Support marker core range in sdk (source/lib/rocprofiler-sdk)

Transition rocprofiler-sdk-tool and output lib to use marker core range

Misc fixes for tests

Fix logic in lib/output/generate{CSV,Stats}.cpp

Update tests/rocprofv3/tracing-hip-in-libraries (marker validation)

Fix test_otf2_data

* Test fixes
