opentelemetry-cpp: Detect cppstd and CXX version

[steinerthomas]

Specify library name and version: opentelemetry-cpp/1.14.2

Fixes #24229

---

• I've read the contributing guidelines.
• I've used a recent Conan client version close to the currently deployed.
• I've tried at least one configuration locally with the conan-center hook activated.

We'll probably need to rebuild the missing binary before this can build :)

Thanks a lot!

@steinerthomas could you check if the current approach works for you? I've simplified the approach as now we don't have to support Conan 1 anymore

[jcar87]

Bear in mind that the original issue is to support Conan 1x #24229
but as of this week it is no longer supported

[AbrilRBS]

Yay! This finally passes, and I can confirm that it also compiles on Macos. Seeing this, I'll revert some changes to be able to merge the fixes for with_stl=True, thanks again a lot for your patience and taking the time to push this PR to the finish line @steinerthomas, we appreciate it :)

[AbrilRBS]

In fact, seems like we need a newer compiler in case of with_stl=True, as seen in https://c3i.jfrog.io/artifactory/cci-build-logs/cci/prod/PR-24230/11/package_build_logs/build_log_opentelemetry-cpp_1_17_0_e4a27418867a8a563233363e2c102cd1_0a22d92ade802089eff409be2e737bce98bbc7b3.txt

Forgot to mention, this comes from https://github.com/open-telemetry/opentelemetry-cpp/blob/v1.9.1/CMakeLists.txt#L128

@AbrilRBS looks good to me. I can't test this right now in production, because we still use conan 1. But I hope we can switch to conan 2 soon.
