fix(xcode.application): avoid duplicate bundle rpath insertion

Only add the macOS app bundle framework rpath if it is missing from the copied app binary.

This avoids install_name_tool failing when the target already links with @executable_path/../Frameworks, for example via add_rpathdirs().

Add a regression test covering a macOS app target that already carries the bundle rpath before xcode.application generates the app bundle.
