Fix symlinked swift-experimental-destination invocations (#6382)

`swift experimental-destination` subcommands no longer work and always display help output. This is a regression introduced in #6362 after making `SwiftDestinationTool` conform to  `AsyncParsableCommand` instead of `ParsableCommand` but not updating `swift-package-manager` command sources to call `async` overload of `main()` function on `SwiftDestinationTool`.
