Fix #1158 Using Delayed Appearance and Focus

[thecoolwinter]

Description

Adds a WindowCodeFileView that wraps CodeFileView but delays it's appearance until a window is available. It also focuses the code file on appearance. These changes are isolated to a single-file window and CodeFileView is left unchanged as to not break any workspace windows.

Thank you to @garethng for the initial work on this in #1174.

While I think this fix is more a hack than a fix, it works so that's fine I guess :)

I agree it does seem a little hacky but it feels safer than a DispatchQueue call and keeps it in SwiftUI.

Hacky but I guess it works for now 😄
