Need a way to provide system defines and system includes when compiler querying is disabled (with compilerPath of "").

It's possible to disable compiler querying (and disable fallback to a different compiler on failure) by specifying a compilerPath of "". This also works in combination with a custom configuration provider or compile_commands.json, to prevent use of the compiler they indicate (in case it's not cl.exe, gcc, or a gcc variant we can query). However, the defines and includes from c_cpp_properties.json are not currently getting merged into the configuration in those cases. Since no compiler will be queried, it seems necessary to support a way for the user to provide the missing system includes and systems defines.

This issue tracks merging in the includes and defines from c_cpp_properties.json when a compilerPath of "" is used in combination with a custom configuration provider or compile_commands.json.

Rastrea cómo se combina c_cpp_properties.json cuando compilerPath está vacío y un proveedor de configuración personalizado o compile_commands.json proporciona la configuración. Verifica el comportamiento con configuraciones en las que la consulta al compilador está deshabilitada y, después, asegúrate de que los includes del sistema y los defines proporcionados por el usuario estén presentes sin consultar a un compilador.
