Add -Wno-error=cpp on App's default Cmake file (#37516)

Summary:
Pull Request resolved: #37516

This will fail build failures from apps which are using libraries which imports
```
#include <react/renderer/graphics/conversions.h>
```
That's just a warning but our usage of `-Wall -Werror` is causing this to fail user builds.

More context on this issue here:
reactwg/react-native-releases#54 (comment)

We can revert this `-Wno-error` once we're on 0.73 as that specific #warning will be entirely
removed from the codebase.
