Add the ability to disable certain linter errors

Type: LanguageService

Many people use g++ (MinGW on Windows), and I am also like this. g++ extends some C99 features in C++, such as array lengths that can be defined with variables which is considered a error by VS Code.

auto a = new int[l]; in standard C++.
auto a[l]; in g++ and C99.

I know that defining with a const is a standard C++ convention, and it is also common sense. But in some cases (such as algorithms), it is convenient to use variable definitions.

I think it's a good idea to let me remove some of the error.(because VS Code is a. editor that doesn't know how the compiler handles certain "errors") Add a point to disable the static error prompt in source, in file or in global setting. Just like in user settings, we can list all static error types.

We can also make g++ specification. This specification remove some features which are not supported in VS Code. The default is the original specification. But when I use g++ in tasks.json, it can automatically enable. It seems that there is a similar error specification function in VS.

Start by reviewing the LanguageService diagnostics described in the issue and the examples of standard C++ versus g++ behavior. Determine how source, file, and global settings would relate to disabling static errors or selecting a g++ specification; done means the requested configuration behavior is defined and supported.
