Fix ordering of diagnostics scheme options (#704)

- The ordering for the runtime checker (main thread, thread performance) were incorrect
- This aligns the order with the order created by Xcode

Test Plan:

- Verify order matches that created by Xcode

e.g.

```xml
<TestAction
      buildConfiguration = "Debug"
      selectedDebuggerIdentifier = "Xcode.DebuggerFoundation.Debugger.LLDB"
      selectedLauncherIdentifier = "Xcode.DebuggerFoundation.Launcher.LLDB"
      customLLDBInitFile = "/bar/foo"
      shouldUseLaunchSchemeArgsEnv = "YES"
      disableMainThreadChecker = "YES"
      language = "en"
      region = "GB"
      localizableStringsDataGatheringEnabled = "YES">
      <Testables>
      </Testables>
   </TestAction>
   <LaunchAction
      buildConfiguration = "Debug"
      selectedDebuggerIdentifier = "Xcode.DebuggerFoundation.Debugger.LLDB"
      selectedLauncherIdentifier = "Xcode.DebuggerFoundation.Launcher.LLDB"
      customLLDBInitFile = "/foo/bar"
      disableMainThreadChecker = "YES"
      disablePerformanceAntipatternChecker = "YES"
      launchStyle = "0"
      useCustomWorkingDirectory = "NO"
      ignoresPersistentStateOnLaunch = "NO"
      debugDocumentVersioning = "YES"
      debugServiceExtension = "internal"
      allowLocationSimulation = "YES">
      <BuildableProductRunnable
         runnableDebuggingMode = "0">
         <BuildableReference
            BuildableIdentifier = "primary"
            BlueprintIdentifier = "FB9BD24F2872C2BB00F272D3"
            BuildableName = "AppWithExts.app"
            BlueprintName = "AppWithExts"
            ReferencedContainer = "container:AppWithExts.xcodeproj">
         </BuildableReference>
      </BuildableProductRunnable>
   </LaunchAction>
```
