Merge pull request #25909 from gblikas:patch-1 
Update intrin_wasm.hpp #25909

See https://github.com/microsoft/vcpkg/issues/33443 for some build context when using 

```vcpkg install opencv4:wasm32-emscripten```

`__EMSCRIPTEN_major__`, `__EMSCRIPTEN_minor__` and `__EMSCRIPTEN_tiny__` in `emsdk` >= 3.1.4 are in a header, as opposed to command line. 

We could potentially be more aggressive with how I'm checking this property; let me know if I should make the change. 

It should also be suggested that `-msimd128` is auto-included in the associated portfile for opencv, but that's a separate issue. Someone let me know if I should also make that change as well. 

Special thanks to https://github.com/youar for supporting this work; please inform if applying a copyright-header is appropriate attribution.

OpenCV.js Performance Test

Node.js Version

Prerequisites

  1. node.js, npm: Make sure you have installed these beforehand with the system package manager.

  2. Benchmark.js: Make sure you have installed Benchmark.js by npm before use. Please run npm install in the directory <build_dir>/bin/perf.

How to Use

For example, if you want to test the performance of cvtColor, please run perf_cvtcolor.js by node in terminal:

node perf_cvtcolor.js

All tests of cvtColor will be run by above command.

If you just want to run one specific case, please use --test_param_filter="()" flag, like:

node perf_cvtcolor.js --test_param_filter="(1920x1080, COLOR_BGR2GRAY)"

Browser Version

How to Use

To run performance tests, please launch a local web server in <build_dir>/bin folder. For example, node http-server which serves on localhost:8080.

Navigate the web browser to the kernel page you want to test, like http://localhost:8080/perf/imgproc/cvtcolor.html.

You can input the parameter, and then click the Run button to run the specific case, or it will run all the cases.
