Add ETW instrumentation to allow profilers to map JITed code to function names

Feature or enhancement

Proposal:

For Linux and macOS, currently cpython has perf maps/jitdump support (macOS support is added in #136461)

In here, Jeff mentioned that Windows support is possible through ETW JSCRIPT9::MethodLoad events instead of jitdump: https://github.com/python/cpython/pull/136461#issuecomment-3104217608

This will allow samply and also Windows Performance Analyzer to read and inject these JITed function names.

Firefox and Chrome both emit these events for jitted JS code:

https://bugs.chromium.org/p/v8/issues/detail?id=11043

Note: ETW stands for Event Tracing for Windows

Has this already been discussed elsewhere?

Links to previous discussion of this feature:

#136461.

Beginne mit der im Issue verlinkten Dokumentation zu perf maps und jitdump, lies anschließend die Diskussion in #136461 und vergleiche die dort referenzierten Implementierungen von Firefox, Chromium, UnityEtwSymbols und ChakraCore. Als abgeschlossen gilt die Aufgabe, wenn Windows-ETW-Ereignisse Namen und Adressen von JITed-Python-Funktionen offenlegen, sodass samply und Windows Performance Analyzer sie zuordnen können.
