Kevin Cooper e443b7379e More verbose error messages for iOS

Summary:
Output the reason for the error when failing to load source code. This was a big help when trying to diagnose https://github.com/facebook/react-native/issues/13299.

~~Unfortunately there still seems to be no way to get the offending line number (because `loadError.userInfo[RCTJSStackTraceKey]` is empty), but this is good enough.~~

Before:

```
[warn][tid:com.facebook.react.JavaScript][RCTBatchedBridge.m:510] Failed to execute source code. Unhandled JS Exception: SyntaxError
```

After:

```
[warn][tid:com.facebook.react.JavaScript][RCTJSCErrorHandling.mm:30] Couldn't get stack trace for http://localhost:8081/index.ios.bundle?platform=ios&dev=true&minify=false:81886
[warn][tid:com.facebook.react.JavaScript][RCTBatchedBridge.m:510] Failed to execute source code. Unhandled JS Exception: SyntaxError Unexpected keyword 'var'
```
Closes https://github.com/facebook/react-native/pull/13561
