runtime: tvOS: Mono runtime for device is missing bitcode

Trying to link with libmonosgen-2.0.dylib from the tvOS runtime pack yields:

ld: ‘/Users/rolf/work/maccore/coreclr/xamarin-macios/builds/downloads/microsoft.netcore.app.runtime.tvos-arm64/6.0.0-preview.1.21102.12/runtimes/tvos-arm64/native/libmonosgen-2.0.dylib’ does not contain bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. file ‘/Users/rolf/work/maccore/coreclr/xamarin-macios/builds/downloads/microsoft.netcore.app.runtime.tvos-arm64/6.0.0-preview.1.21102.12/runtimes/tvos-arm64/native/libmonosgen-2.0.dylib’

This is also evident in the size difference between the runtime pack and the old mono archive:
