fix(xcode.application): use the correct framework rpath for iOS apps

Use @executable_path/Frameworks for iphoneos application bundles when
embedding dependent frameworks.

The existing @executable_path/../Frameworks rpath is correct for macOS
app layout, but incorrect for iOS where the executable lives directly in
MyApp.app and embedded frameworks live in MyApp.app/Frameworks.

Add a regression test that builds an iOS simulator app with an embedded
framework and verifies the generated LC_RPATH.
