API version error seen while running using ort python whls built from src

[MayureshV1]

Describe the issue

On upgrading to latest ort-main the following issue was seen while running a Python based app:
The requested API version [25] is not available, only API versions [1, 24] are supported in this build. Current ORT Version is: 1.25.0

This error occurs during model compilation phase and is seen on OpenVINO EP.

Issue cannot be reproduced when building whl package from https://github.com/microsoft/onnxruntime/commits/v1.24.1

To reproduce

1. Build from src using ort-main commit: 06fe9a4
2. Generate Python whl packages using -build_wheel
3. Compile a model using Pythion based app on OpenVINO EP using onnxruntime_perf_test.exe

Urgency

High- Blocks internal CI and app development bit not blocking production apps.

When upgrading to ORT 1.25, the stated error occurs int the call to register_custom_ops_library() in this scenario:
so = onnxruntime.SessionOptions()
so.register_custom_ops_library(_lib_path())

It appears to be caused from this function in onnxruntime\core\session\onnxruntime_c_api.cc (4863-ish)
ORT_API(const OrtApi*, OrtApis::GetApi, uint32_t version) {
if (version >= 1 && version <= ORT_API_VERSION)
return &ort_api_1_to_25;

fprintf(stderr,
"The requested API version [%u] is not available, only API versions [1, %u] are supported in this build."
" Current ORT Version is: %s\n",
version, ORT_API_VERSION, ORT_VERSION);

return nullptr; // Unsupported version
}
