Add model compilation in ORT perf test (#25797)
This PR adds model compilation support in ort perf test
* Add `--compile_ep_context` flag in onnxruntime_perf_test. This
generates EP context model and prints out compilation time and perf
statistics for the compiled model
* Prints `Compile time cost` for EP context compilation
Sample usage:
```sh
$ ./onnxruntime_perf_test -e trt-rtx -I -r 1 "/path/to/model.onnx" --compile_ep_context --compile_model_path "/path/to/model_ctx.onnx"
```
Output:
```sh
Compile time cost: 17.8012 s
Session creation time cost: 0.966619 s
First inference time cost: 8151 ms
Total inference time cost: 8.08084 s
