[bug] Conan 2.0.11+ choose wrong default cppstd for apple-clang

[sizeak]

Environment details

• Operating System+version: macOS 13.6
• Compiler+version: apple-clang 14.0
• Conan version: 2.0.11 & 2.0.12
• Python version: 3.11.5

Steps to reproduce

python -m pip install --upgrade conan==2.0.11
conan profile detect --force

I believe this is caused by the removal of

    if compiler != "msvc":
        cppstd = _cppstd_default(compiler, version)
        if compiler == "apple-clang" and version >= "11":
            # forced auto-detection, gnu98 is too old
            cppstd = "gnu17"
        result.append(("compiler.cppstd", cppstd))

Hi @simoncent thanks a lot for taking the time to report the issue, you're totally right, it's a byproduct of moving the detection api in the PR you pointed at. I've submitted #14837 and fixed the relevant tests that made this possible in the first time :)

The fix will be released in the next few days in the 2.0.13 version

Excellent, thanks for the quick remediation.
