Need to set NSLocalNetworkUsageDescription via Projucer

[cxhawk]

Since macos 15 app is required to get this permission to do local networking. And since 15.5, you are recommended to have NSLocalNetworkUsageDescription to trigger the permission dialoge

Thanks, we’ve added options to set the NSLocalNetworkUsageDescription plist entry from Projucer and CMake:

CMake: Allow setting NSLocalNetworkUsageDescription on Apple platforms

Projucer: Allow setting NSLocalNetworkUsageDescription for Xcode exporter
