This allows users to set `EXTRA_*FLAGS` variables when using sysbuild. If these flags are provided in both local and global sysbuild scopes, then only the local ones will be used for a given image. This is to circumvent issues with mixing space-separated and `;`-separated lists. Signed-off-by: Grzegorz Swiderski <grzegorz.swiderski@nordicsemi.no>
