We need to make sure that we build swift-backtrace with a deployment target newer than 10.14.4 in order that we get linked against `/usr/lib/swift/libswiftCore.dylib` rather than using an `@rpath`-based path. If we fail to do that, dyld becomes confused and we end up crashing with weird errors about missing method implementations on `Swift.__StringStorage`. To make this work, add support for `DEPLOYMENT_VERSION_*` in the `add_swift_target_executable()` CMake function. And since I spotted a bug in it, fix the existing support in `add_swift_target_library()` while I'm there. rdar://132710670
