Add DeviceInfo in iOS benchmark run (#5410)

Summary:
Given the way iOS benchmark app measures model load time, inference time, and memory usage using `measureWithMetrics` with `XCTClockMetric` and `XCTMemoryMetric`.  I think the easiest way to gather the benchmark metric is to do it after the test finishes and parse the output.

In the same spirit as #5332, this PR adds more information about the device so that it can be parsed later.  I add the information into the test name, shoumikhin plz let me know if you know a better way to pass this information around.

The output looks like this with the information in the test case name, i.e. `test_forward_models_llama2_iPhone_iPhone14,2_iOS_17.6.1`

```
