Build for Android failing: error: no template named 'unordered_map' in namespace 'std'

Nobody has claimed this yet.

**Describe the bug**
When building onnxruntime-genai for Android on Windows using OpenJDK 21, NDK 25.2, and CMake 3.31.6, the build fails with errors ```error: no template named 'unordered_map' in namespace 'std'; did you mean 'nlohmann::ordered_map'?```
I also tried to build the project under Linux with JDK 17 and NDK 25.2 and got the same errors.

**ChatGPT problem idea:**
> The error message suggests a potential conflict with `nlohmann::ordered_map`. This issue appears to be caused by missing includes in the generated onnxruntime-extensions source files (for example, in `tokenizer_common.h` and `c_api_utils.hpp`).

**To Reproduce**
Steps to reproduce the behavior:
1. Clone the onnxruntime-genai repository.
2. Try to build the project:
```
python build.py --build_java --android --android_home "[...]\AppData\Local\Android\Sdk" --android_ndk_path "[...]\AppData\Local\Android\Sdk\ndk\25.2.9519653" --android_abi arm64-v8a --config Release
```
3. The build fails with errors:
```
error: no template named 'unordered_map' in namespace 'std'
```

**Expected behavior**
The build should complete successfully. The project should include the proper headers (e.g., ``) so that `std::unordered_map` is correctly recognized by the compiler.

**Desktop:**
- OS: Windows 11
- Compiler: Clang (Android NDK 25.2)
- CMake: 3.31.6

Start with build.py and reproduce the Android build using the reported NDK, CMake, and ABI settings. Inspect the onnxruntime-extensions tokenizer sources, especially tokenizer_common.h, c_api_utils.hpp, bpe_kernels.cc, and the related headers, then confirm the build completes successfully for Android.
