After #185537, `lldb-server` would crash with an assertion because it calls`exit()` instead of returning from `main`. This means that we never get an opportunity to call `Terminate` before the static `SystemLifetimeManager` is destroyed. I could've created a static RAII object to wrap this in (similar to what Aiden did in #186133) but that's not necessary. I updated the helper functions to return an `llvm::Error` while `main_gdbserver` and `main_platform` now return an `int`. Fixes #186207
