[iOS] Unity's profiler device memory consumption is different from consumption shown by XCode
Steps to reproduce:
1. Create a new Unity project
2. Build to iOS with "Development mode" and "Autoconnect profiler"
3. Open the project with Xcode
4. Build & Run on an iOS device
5. In Unity, attach the profiler to the running app
6. Check the memory consumption shown on profiler
7. Check memory consumption in Xcode's Debug Navigator
Expected results: memory consumption is the same in both tools
Actual results: Unity profiler shows a lower number (~20MB) compared to Xcode's Debug Navigator (~30MB)
Reproduced on: 5.5.4p1, 5.6.2f1, 2017.1.0f1, 2017.2.0b1

Resolution Note (2020.1.X):
Unity Profiler's Total Reserved (and Used) Memory shows memory usage information which Unity counts.
Memory usage in XCode can be higher or lower depending on resident/paged situation and how many allocations came from native plugins.
The Total System Used Memory being 0 in the thread is a bug. It has been fixed separately to report resident size and is being backported.
