Allow disabling colors in the output

### Describe the issue

`onnxruntime/core/common/logging/sinks/ostream_sink.cc` defines message color activator sequences and then uses them unconditionally. When redirecting this output into a file, it becomes less readable. Would be great to have an option to disable the use of colors in the output.

### To reproduce

Here is an example of the output captured by the logging system:
```
2025/01/07 00:02:06 [stderr] 2025-01-07 00:02:06.180133144 [E:onnxruntime:Default, provider_bridge_ort.cc:1862 TryGetProviderInfo_CUDA] /onnxruntime_src/onnxruntime/core/session/provider_bridge_ort.cc:1539 onnxruntime::Provider& onnxruntime::ProviderLibrary::Get() [ONNXRuntimeError] : 1 : FAIL : Failed to load library libonnxruntime_providers_cuda.so with error: libcudnn.so.9: cannot open shared object file: No such file or directory

Start with onnxruntime/core/common/logging/sinks/ostream_sink.cc, where the color escape sequences are defined and used unconditionally. Trace how logging options reach this sink and identify the appropriate configuration path for disabling colors. Done means redirected output can omit the color sequences while preserving the existing log messages.
