Improve error thrown when starting remotedebug-ios-webkit-adapter server

[ewanharris]

Describe the Bug

Currently when we start the adapter that handles the WebKit -> CDP translation for us we just throw the error we received https://github.com/appcelerator/vscode-appcelerator-titanium/blob/d9c47ba782fd3bb6dfcf63fc00aa8852ccdc19c9/src/debugger/titaniumDebugAdapter.ts#L115-L121

This is pretty pointless as nothing of use gets surfaced to the user as we can't pull the logs of the server from what I can tell and we just show Error processing "launch": {_stack }

We might need to come up with a guide that helps people fix this error pointing to common problems, and how to debug the issue.

For me the issue was I had to reinstall libimobiledevice as it was failing to load libusbmuxd.
