Allow python 3.12 in attach code

[AdamYoblick]

Creating this PR so the dll's get generated through github actions. Once they are available as artifacts, I will download them and test locally.

Downloading windows artifacts from https://github.com/microsoft/debugpy/actions/runs/8993404815?pr=1580 and testing attach scenario locally.

The attach DOES work now, we got past the "unknown python version" errors. But breakpoints are not getting hit like they were in when using python 3.11.

@int19h - I know debugpy works with python 3.12, but is there anything special I need to do to the attach code for breakpoints to be hit when attaching? This scenario works for 3.11 but not 3.12. Thanks!

The other place that needs to be updated is here. Without this DLL, it will not be able to set tracing on existing threads.

debugpy/src/debugpy/_vendored/pydevd/pydevd_tracing.py

Lines 252 to 256 in 09b5af0

	def _load_python_helper_lib_uncached():
	if (not IS_CPYTHON or sys.version_info[:2] > (3, 11)
	or hasattr(sys, 'gettotalrefcount') or LOAD_NATIVE_LIB_FLAG in ENV_FALSE_LOWER_VALUES):
	pydev_log.info('Helper lib to set tracing to all threads not loaded.')
	return None

But then the DLL itself needs to implement this function for Python 3.12:

debugpy/src/debugpy/_vendored/pydevd/pydevd_attach_to_process/common/py_custom_pyeval_settrace.hpp

Lines 6 to 8 in 09b5af0

	#include "py_custom_pyeval_settrace_common.hpp"
	#include "py_custom_pyeval_settrace_310.hpp"
	#include "py_custom_pyeval_settrace_311.hpp"

debugpy/src/debugpy/_vendored/pydevd/pydevd_attach_to_process/common/py_custom_pyeval_settrace.hpp

Lines 170 to 190 in 09b5af0

	void InternalPySetTrace(PyThreadState* curThread, PyObjectHolder* traceFunc, bool isDebug, PythonVersion version)
	{
	if (PyThreadState_25_27::IsFor(version)) {
	InternalPySetTrace_Template<PyThreadState_25_27*>(reinterpret_cast<PyThreadState_25_27*>(curThread), traceFunc, isDebug);
	} else if (PyThreadState_30_33::IsFor(version)) {
	InternalPySetTrace_Template<PyThreadState_30_33*>(reinterpret_cast<PyThreadState_30_33*>(curThread), traceFunc, isDebug);
	} else if (PyThreadState_34_36::IsFor(version)) {
	InternalPySetTrace_Template<PyThreadState_34_36*>(reinterpret_cast<PyThreadState_34_36*>(curThread), traceFunc, isDebug);
	} else if (PyThreadState_37_38::IsFor(version)) {
	InternalPySetTrace_Template<PyThreadState_37_38*>(reinterpret_cast<PyThreadState_37_38*>(curThread), traceFunc, isDebug);
	} else if (PyThreadState_39::IsFor(version)) {
	InternalPySetTrace_Template<PyThreadState_39*>(reinterpret_cast<PyThreadState_39*>(curThread), traceFunc, isDebug);
	} else if (PyThreadState_310::IsFor(version)) {
	// 3.10 has other changes on the actual algorithm (use_tracing is per-frame now), so, we have a full new version for it.
	InternalPySetTrace_Template310<PyThreadState_310*>(reinterpret_cast<PyThreadState_310*>(curThread), traceFunc, isDebug);
	} else if (PyThreadState_311::IsFor(version)) {
	InternalPySetTrace_Template311<PyThreadState_311*>(reinterpret_cast<PyThreadState_311*>(curThread), traceFunc, isDebug);
	} else {
	printf("Unable to set trace to target thread with Python version: %d", version);
	}
	}

That is the trickiest part. This is the implementation for Python 3.11, and I believe much of this has changed for 3.12 (e.g. use_tracing doesn't even exist anymore):

we can also add python 3.13?
