Abhishek Gola 8cc3f68cd4 Merge pull request #28964 from abhishek-gola:extend_primitive_core_ops
Extended primitive core operations to support new types #28964

The support was already there, this PR tests them on edge cases and patch the fix.

Vadim Pisarevsky 1d18aba587 Extended several core functions to support new types (#24962)
* started adding support for new types (16f, 16bf, 32u, 64u, 64s) to arithmetic functions

* fixed several tests; refactored and extended sum(), extended inRange().

* extended countNonZero(), mean(), meanStdDev(), minMaxIdx(), norm() and sum() to support new types (F16, BF16, U32, U64, S64)

* put missing CV_DEPTH_MAX to some function dispatcher tables
* extended findnonzero, hasnonzero with the new types support

* extended mixChannels() to support new types

* minor fix

* fixed a few compile errors on Linux and a few failures in core tests

* fixed a few more warnings and test failures

* trying to fix the remaining warnings and test failures. The test `MulTestGPU.MathOpTest` was disabled - not clear whether to set tolerance - it's not bit-exact operation, as possibly assumed by the test, due to the use of scale and possibly limited accuracy of the intermediate floating-point calculations.

* found that in the current snapshot G-API produces incorrect results in Mul, Div and AddWeighted (at least when using OpenCL on Windows x64 or MacOS x64). Disabled the respective tests.

Kumataro bae435a5a7 Merge pull request #24578 from Kumataro:fix_verify_unsupported_new_mat_depth
Fix verify unsupported new mat depth for nonzero/minmax/lut #24578

`cv::LUI()`, `cv::minMaxLoc()`, `cv::minMaxIdx()`, `cv::countNonZero()`, `cv::findNonZero()` and `cv::hasNonZero()` uses depth-based function table. However, it is too short for `CV_16BF`, `CV_Bool`, `CV_64U`, `CV_64S` and `CV_32U` and it may occur out-boundary-access. This patch fix it. And If necessary, when someone extends these functions to support, please relax this test.
