Fix issues in RISC-V Vector (RVV) Universal Intrinsic #27006 This PR aims to make `opencv_test_core` pass on RVV, via following two parts: 1. Fix bug in Universal Intrinsic when VLEN >= 512: - `max_nlanes` should be multiplied by 2, because we use LMUL=2 in RVV Universal Intrinsic since #26318. - Related tests are also expanded to match longer registers - Relax the precision threshold of `v_erf` to make the tests pass 2. Temporary fix #26936 - Disable 3 Universal Intrinsic code blocks on GCC - This is just a temporary fix until we figure out if it's our issue or GCC/something else's This patch is tested under the following conditions: - Compier: GCC 14.2, Clang 19.1.7 - Device: Muse-Pi (VLEN=256), QEMU (VLEN=512, 1024) ### Pull Request Readiness Checklist See details at https://github.com/opencv/opencv/wiki/How_to_contribute#making-a-good-pull-request - [x] I agree to contribute to the project under Apache 2 License. - [x] To the best of my knowledge, the proposed patch is not based on a code under GPL or another license that is incompatible with OpenCV - [ ] The PR is proposed to the proper branch - [ ] There is a reference to the original bug report and related work - [ ] There is accuracy test, performance test and test data in opencv_extra repository, if applicable Patch to opencv_extra has the same branch name. - [ ] The feature is well documented and sample code can be built with the project CMake
