ONNX Runtime will perform feature detection based on the value of this property. Specifically, when the value is set to:

• undefined, true or "fixed": will check availability of Fixed-width SIMD.
• "relaxed": will check availability of Relaxed SIMD.
• false: will not perform SIMD feature checking.

Setting this property does not make ONNX Runtime to switch to the corresponding runtime automatically. User need to set wasmPaths or wasmBinary property to load the corresponding runtime.
