Add support for C23/C++26 #embed

[Stovent]

Feature Request

I couldn't find any issue regarding that before so I apology if it's a duplicate.

C23/C++26 added support for #embed preprocessor macro, and GCC 15/Clang 19 implemented the feature so it's now usable. But Intellisense doesn't recognize the directive.

If implementing the complete parsing and semantics of it is complicated to implement, is it possible to simple recognize #embed as a valid directive please?

It's not implemented by our IntelliSense parser yet. You can track the progress in the #embed row and EDG column at https://en.cppreference.com/w/cpp/compiler_support.html

Wow, EDG is behind on everything. Is there a way to set an alternate source for intellisense? Maybe llvm or something? Would be convenient to use C23's #embed.

[sean-mcmanus]

@sdegutis Not with our C/C++ extension.

Is there some way to suppress the "unrecognized preprocessing directive" error for a line or file as a workaround?
