videoio: add Orbbec Gemini 330 camera support #27230

### Description of Changes
#### motivated:
- Orbbec has launched a new RGB-D camera — the Gemini 330. To fully leverage the capabilities of the Gemini 330, Orbbec simultaneously released version 2 of the open-source OrbbecSDK. This PR adapts the support for the Gemini 330 series cameras to better meet and respond to users’ application requirements.
#### change:
- Add support for the Orbbec Gemini330 camera.
- Fixed an issue with Femto Mega on Windows 10/11; for details, see [issue](https://github.com/opencv/opencv/pull/23237#issuecomment-2242347295).
- When enabling `HAVE_OBSENSOR_ORBBEC_SDK`, the build now fetches version 2 of the OrbbecSDK, and the sample API calls have been updated to the v2 format.

### Testing
|     OS     |                Compiler                 |      Camera       | Result |
|:----------:|:---------------------------------------:|:-----------------:|:------:|
| Windows 11 | (VS2022) MSVC runtime library version 14.40       | Gemini 335/336L   | Pass   |
| Windows 11 | (VS2022) MSVC runtime library version 14.19       | Gemini 335/336L   | Pass   |
| Ubuntu22.04| GCC 11.4                               | Gemini 335/336L   | Pass   |

Merge pull request #27228 from utibenkei:fix_java_enum_wrapper
Explicitly specify enum type scopes to improve Java wrapper generation #27228 

Changed DataLayout and ImagePaddingMode to dnn::DataLayout and dnn::ImagePaddingMode to explicitly specify their scopes. This allows gen_java.py to correctly register  disc_type, preventing constructors and methods using these enum types from being skipped during Java wrapper generation.

Similarly updated QRCodeEncoder::CorrectionLevel and QRCodeEncoder::EncodeMode with explicit scope declarations.

Also added a new Java test class `DnnBlobFromImageWithParamsTest` based on: https://github.com/opencv/opencv/blob/4.x/modules/dnn/test/test_misc.cpp#L133-L243

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.

Merge pull request #27154 from kinchungwong:logging_callback_simple_c
User-defined logger callback, C-style. #27154

This is a competing PR, an alternative to #27140 

Both functions accept C-style pointer to static functions. Both functions allow restoring the OpenCV built-in implementation by passing in a nullptr.
- replaceWriteLogMessage
- replaceWriteLogMessageEx

This implementation is not compatible with C++ log handler objects.

This implementation has minimal thread safety, in the sense that the function pointer are stored and read atomically. But otherwise, the user-defined static functions must accept calls at all times, even after having been deregistered, because some log calls may have started before deregistering.

Merge pull request #27119 from amane-ame:warp_hal_rvv
Add RISC-V HAL implementation for cv::warp series #27119

This patch implements `cv_hal_remap`, `cv_hal_warpAffine` and `cv_hal_warpPerspective` using native intrinsics, optimizing the performance of `cv::remap/cv::warpAffine/cv::warpPerspective` for `CV_HAL_INTER_NEAREST/CV_HAL_INTER_LINEAR/CV_HAL_INTER_CUBIC/CV_HAL_INTER_LANCZOS4` modes.

Tested on MUSE-PI (Spacemit X60) for both gcc 14.2 and clang 20.0.

```
$ ./opencv_test_imgproc --gtest_filter="*Remap*:*Warp*"
$ ./opencv_perf_imgproc --gtest_filter="*Remap*:*remap*:*Warp*" --perf_min_samples=200 --perf_force_samples=200
```
