clang-tidy support for extended floating-point types

Discussed in #10595

With

"C_Cpp.default.cppStandard": "c++23",
"C_Cpp.default.compilerPath": "/usr/bin/g++-13"

The following code:

int main()
{
    _Float16 f;
}

causes _Float16 is not supported on this target C/C++(clang-diagnostic-error).

However, running clang-tidy directly produces no warnings or errors.

@blackteahamburger You can use "C_Cpp.codeAnalysis.clangTidy.args": ["--extra-arg=-msse2"] as a workaround.

The fix is available with 1.15.0 (pre-release): https://github.com/microsoft/vscode-cpptools/releases/tag/v1.15.0

However, there is still no _Float32, _Float64 or _Float128 support.

@blackteahamburger That is due to clang(-tidy) itself not having support for that.
