Xcode 15: Script sandboxing

[hvge]

The Xcode 15 added a new feature called "script sandboxing" that makes custom scripts more safe to run on developer's machine. To be fully compatible with this feature, our build system must generate an exhaust list of files that are accessed from our support scripts.

For example, xcbuild-helper.sh re-creates openssl.framework in the architecture specific build folder according to the actual platform and architecture. To make this compatible with the script sandboxing, we have to create a new build step, that populate content of openssl.xcframework into .xcfilelist and then we have to use that file as an exclusion rule to the actual build step.
