Backport 124b19d from #15434

3.19 branch still has Stack v1, which pushes class_name to profile Samples. Given that this fixes crashing bugs, it would be more beneficial to have this than losing some tiny bit of information for code path that is mostly deprecated.

We've been seeing a low number of crashes that have the following stack traces.

PyFrame_FastToLocalsWithError
_PyObject_GenericGetAttrWithDict
__pyx_f_7ddtrace_9profiling_9collector_10_traceback__extract_class_name.constprop.0
__pyx_pw_7ddtrace_9profiling_9collector_10_traceback_5pyframe_to_frames

which corresponds to value = frame.f_locals[argname] in extract_class_name() function.

Fore more details see notebook,
https://app.datadoghq.com/notebook/13515661/pyframe-to-frames-crashes

The reason this could lead to a crash is that the frame could be in an invalid state, partially deallocated, or corrupted. And this doesn't happen on our stack sampler (Echion) as it doesn't use it, and just use co_qualname (Python 3.11+) or co_name (Python < 3.11)

This code is no longer needed as we don't use class_name field from DDFrame named tuple. Memory profiler has been putting an empty string. Lock profiler populated it but then it didn't export it in the sample.

More appropriate way to populate the class name for Python versions 3.11+ would be using co_qualname as Echion does. I'll follow up with this in a separate PR. And this is why we see fully qualified name on our CPU time view, but function name only on memory/lock views.

We've been seeing a low number of crashes that have the following stack
traces.

```
PyFrame_FastToLocalsWithError
_PyObject_GenericGetAttrWithDict
__pyx_f_7ddtrace_9profiling_9collector_10_traceback__extract_class_name.constprop.0
__pyx_pw_7ddtrace_9profiling_9collector_10_traceback_5pyframe_to_frames
```

which corresponds to `value = frame.f_locals[argname]` in
`extract_class_name()` function.

Fore more details see notebook,
https://app.datadoghq.com/notebook/13515661/pyframe-to-frames-crashes

The reason this could lead to a crash is that the `frame` could be in an
invalid state, partially deallocated, or corrupted. And this doesn't
happen on our stack sampler (Echion) as it doesn't use it, and just use
`co_qualname` (Python 3.11+) or `co_name` (Python < 3.11)

This code is no longer needed as we don't use `class_name` field from
`DDFrame` named tuple. Memory profiler has been putting an empty string.
Lock profiler populated it but then it didn't export it in the sample.

More appropriate way to populate the class name for Python versions
3.11+ would be using `co_qualname` as Echion does. I'll follow up with
this in a separate PR. And this is why we see fully qualified name on
our CPU time view, but function name only on memory/lock views.
