Module cache now supports library products (static and dynamic)

Static and dynamic library targets can now be cached alongside frameworks in the module cache. Cache warm builds library XCFrameworks with xcodebuild -create-xcframework -library, including public headers when present. On restore, Tuist exposes cached library Swift module directories and public headers as search paths. Mixed graphs can now reuse library modules from the cache instead of rebuilding them from source. (Requires TuistCacheEE.)
