Option to remove intellisense errors from the problems window

Hi! Due to an issue I'm having with CMake tools similar to 4350 (and also another proprietary extension that also feed data to C/C++ intellisense), I'm experiencing a very frequent barrage of intellisense errors whenever I open files. All these errors go into the problems pane/window and obfuscate (mix with) the real compilation errors that happen there when building, making them harder to find.

In fact, if a file is not opened and you click on a build error, all intellisense errors will suddenly appear, displacing the build errors, which can also be jarring even if the intellisense errors are legitimate.

Regardless of the issue, it occurs to me that a simple setting to allow the user to disable this feature would be helpful to users. It would definitely be helpful to me.

There's also personal preference. I don't think I personally find value on listing the intellisense errors in the pane even if intellisense works perfectly. The squiggles are very useful while editing, but for a more project-wide error list the compiler will be the ultimate source of truth.

Riproduci l’interazione tra C/C++ IntelliSense diagnostics e la VS Code Problems window, incluso lo scenario CMake Tools collegato nell’issue. Inizia tracciando il modo in cui IntelliSense errors vengono aggiunti al Problems pane; il lavoro è completo quando gli utenti possono disabilitare queste voci mantenendo editor squiggles e compiler errors.
