Currently NanoRT does not utilize SIMD/AVX.
Also no quantized BVH support.
It'd be better to start to consider optimization and quantization.
Fortunately, recent CPU architecture(AlderLake, Z…

The SIMD cannot be disabled anymore. These are the 2 parts we need to fix:
- [x] do not put `-msimd128` to `emcc-default.rsp`, otherwise we compile with SIMD even when `WasmEnableSIMD` is `false`. …

We should document the various env vars (`{}ARROW_SIMD_LEVEL{`}, `{}ARROW_RUNTIME_SIMD_LEVEL{`}, `{}ARROW_USER_SIMD_LEVEL{`}, others?).
We should also document what the defaults are (and what that …
