Merge pull request #27060 from YooLc:hal-rvv-integral 
[hal_rvv] Add cv::integral implementation and more types of input for test #27060

This patch introduces an RVV-optimized implementation of `cv::integral()` in hal_rvv, along with performance and accuracy tests for all valid input/output type combinations specified in `modules/imgproc/src/hal_replacement.hpp`:
2a8d4b8e43/modules/imgproc/src/hal_replacement.hpp (L960-L974)

The vectorized prefix sum algorithm follows the approach described in [Prefix Sum with SIMD - Algorithmica](https://en.algorithmica.org/hpc/algorithms/prefix/).

I intentionally omitted support for the following cases by returning `CV_HAL_ERROR_NOT_IMPLEMENTED`, as they are harder to implement or show limited performance gains:
1. **Tilted Sum**: The data access pattern for tilted sums requires multi-row operations, making effective vectorization difficult.
2. **3-channel images (`cn == 3`)**: Current implementation requires `VLEN/SEW` (a.k.a. number of elements in a vector register) to be a multiple of channel count, which 3-channel formats typically cannot satisfy.
    - Support for 1, 2 and 4 channel images is implemented
4. **Small images (`!(width >> 8 || height >> 8)`)**: The scalar implementation demonstrates better performance for images with limited dimensions. 
    - This is the same as `3rdparty/ndsrvp/src/integral.cpp` 09c71aed14/3rdparty/ndsrvp/src/integral.cpp (L24-L26)

Test configuration:

- Platform: SpacemiT Muse Pi (K1 @ 1.60 Ghz)
- Toolchain: GCC 14.2.0
- `integral_sqsum_full` test is disabled by default, so `--gtest_also_run_disabled_tests` is needed

Test results:

```

The vectorized implementation shows progressively better acceleration for larger image sizes and higher channel counts, achieving up to 6.21× speedup for 64FC4 (1920×1080) inputs with `DEPTH_64F_64F` configuration.

This is my first time proposing patch for the OpenCV Project 🥹, if there's anything that can be improved, please tell me.

4a297a2443 ts: refactor OpenCV tests 
- removed tr1 usage (dropped in C++17)
- moved includes of vector/map/iostream/limits into ts.hpp
- require opencv_test + anonymous namespace (added compile check)
- fixed norm() usage (must be from cvtest::norm for checks) and other conflict functions
- added missing license headers
