According to the ONNX protobuf specification, boolean tensors may be stored either in raw_data or packed into repeated int32 int32_data as individual 32-bit integers (not a bitmask). Previously, getMatFromTensor only read raw_data, causing assertion failures when parsing ONNX models that serialize boolean initializers into int32_data. This patch adds int32_data extraction with conversion to CV_Bool, adds specification documentation, removes unreachable duplicate branches for UINT16/UINT32/UINT64, and adds tests in test_onnx_importer using models from opencv_extra. Test data in opencv_extra under the same branch name as this patch: https://github.com/opencv/opencv_extra/pull/TBD Addresses #19366.
