CANN: CONV_TRANSPOSE_1D operator: supporting the cases where (op->src[0]->ne[0] - 1) > 255

[Intellouis]

Description

This PR implements support for kernel_size > 255 in the CANN backend for the ggml's CONV_TRANSPOSE_1D operator. The existing CONV_TRANSPOSE_1D operator, implemented via a direct call to Convolution, throws a shape error for inputs whose kernel_size is greater than 255.

Summary of changes:

1. Added the header file aclnnop/aclnn_slice.h to ggml/src/ggml-cann/aclnn_ops.h to support slice operations.

2. Added function implementation in ggml/src/ggml-cann/aclnn_ops.cpp. The general approach is as follows:

• Slice the large kernel into multiple smaller kernels each ≤ 255.
• Perform CONV_TRANSPOSE_1D on each small kernel with the input to obtain partial results.
• Calculate the start and end positions of each partial result within the final output and pad them to the same length as the output.
• Sum all partial results to get the final output.

3. In ggml/src/ggml-cann/ggml-cann.cpp, remove the condition check:

case GGML_OP_CONV_TRANSPOSE_1D:
    // TODO: ((weightL - 1) * dilationW - padLeft)=1336 should not be larger than 255.
    return (op->src[0]->ne[0] - 1) <= 255;

Testing

Test steps:

• Building：

cmake -B build -DGGML_CANN=on -DCMAKE_BUILD_TYPE=release
cmake --build build --config release -j

• Run test:

./bin/test-backend-ops test -b CANN0 -o CONV_TRANSPOSE_1D

All test cases should be passed.
