* use 2 parms for now to identify the error

* Revert "use 2 parms for now to identify the error"

This reverts commit 86faf99.

* replace += with =

* add v_log ref

* refactor intrin_math code

* Add include guard to `intrin_math.hpp` to prevent multiple inclusions

* rename VX to V; make fp64 impl in neon be optional

* add v_setall, v_setzero for all backends; rewrite the intrin_math

* fix error on rvv_scalable

* let v_erf use v_exp_default_32f function

* 1. replaced 'v_setzero(VecType dummy)' with 'v_setzero_<VecType>()'
2. replaced 'v_setall(LaneType x, VecType dummy)' with 'v_setall_<VecType>(LaneType x)'
3. added tests for the new v_setzero_<> and v_setall_<>.

* gcc does not seem to like static_assert in functions even when they are not used

* trying to fix compile errors in Debug mode on Linux

inversion checks

Update intrin_wasm.hpp opencv#25909

See microsoft/vcpkg#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.

- Implemented a new `create` method in `FaceRecognizerSF` to allow model and configuration loading from memory buffers (std::vector<uchar>), similar to the existing functionality in `FaceDetectorYN`.
- Updated `face_recognize.cpp` with a new constructor in `FaceRecognizerSFImpl` that supports buffer-based loading for both model weights and network configuration.
- Ensured compatibility with both file-based and buffer-based model loading by maintaining consistent backend and target settings across both constructors.
- This change improves flexibility, allowing FaceRecognizerSF to be instantiated from memory buffers, which is useful for dynamic model loading scenarios such as embedded systems or applications where models are loaded in-memory.
