623ceb78 - Ensure that `open(::Function, ::Cmd)` waits for termination (#44078)

Ensure that `open(::Function, ::Cmd)` waits for termination (#44078) On Windows, we observed occasional issues where an error within the function callback to the `open(::Function, ::Cmd)` method would cause problems due to assuming that the opened process had finished by the time the `open()` call was finished. In most cases this was true, however on Windows, it was found that we need to explicitly `wait()` upon the process object to ensure that all file handles held by the subprocess were properly closed by the time `open()` is finished.
