C/C++ configs

There are two popular C/C++ plugins: C/C++ IntelliSense provided by Microsoft and Clangd provided by LLVM. Usually, I installed both, but IntelliSense has conflict with Clangd, so I have below configs to disable IntelliSense.

"C_Cpp.default.cppStandard": "c++17",
"C_Cpp.default.defines": [
],
"C_Cpp.default.enableConfigurationSquiggles": false,
"[cpp]": {
},
"C_Cpp.intelliSenseEngine": "disabled",
"clangd.fallbackFlags": [
  "-D_LIBCPP_STD_VER=17"
]

When Clangd is enabled, vscode parses files using Clangd and therefore the macros. For example, when I read llvm source code, there are a lot of codes like #if _LIBCPP_STD_VER >= 17. In order to correctly highlight these blocks, I need to tell Clangd the value of this macro. The vscode clangd plugin has a configuration parameter clangd.fallbackFlags for it. See below logs of how this parameter is used to create the build command.
