[onnx/onnxruntime] `ONNX_DISABLE_STATIC_REGISTRATION=ON` is required for onnx when used with onnxruntime?

Describe the bug
My program that uses onnxruntime show warning messages below at runtime:

Schema error: Trying to register schema with name Abs (domain:  version: 1) from file D:\Coding\vcpkg\buildtrees\onnx\src\v1.19.0-c251c1eccc.clean\onnx\defs\math\old.cc line 2758, but it is already registered from file D:\Coding\vcpkg\buildtrees\onnx\src\v1.19.0-c251c1eccc.clean\onnx\defs\math\old.cc line 2758

... (And many of them)

Environment

• OS: Win10
• Compiler: VS 2022

To Reproduce
Just run some onnx model inference code

Expected behavior
No such warnings.

Additional context
Copilot tells me that ONNX_DISABLE_STATIC_REGISTRATION should be turned on for onnx, and it's actually mentioned here in onnxruntime port.

Start with ports/onnxruntime/portfile.cmake, especially the ONNX_DISABLE_STATIC_REGISTRATION setting mentioned in the issue, and compare how ONNX and onnxruntime are configured. Reproduce the Windows inference case with an ONNX model and verify that the duplicate schema warnings no longer appear.
