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

Links to previous discussion of this feature:

#136461.

Commencez par la documentation de perf maps et jitdump liée dans l’issue, puis lisez la discussion dans #136461 et comparez les implémentations référencées de Firefox, Chromium, UnityEtwSymbols et ChakraCore. C’est terminé lorsque les événements ETW Windows exposent les noms et les adresses des fonctions Python JITed afin que samply et Windows Performance Analyzer puissent les associer.
