Cache library products in the module cache

Static and dynamic library targets can now be selected and cached as binary products in the module cache, alongside framework targets. Cache warm produces library XCFrameworks with xcodebuild -create-xcframework -library, including public headers when the source target declares them. On restore, Tuist wires Swift module directories and public C/Objective-C header directories from cached library XCFrameworks into generated targets, so projects with mixed framework/library graphs can reuse cached binaries without forcing library modules to become frameworks.
