[PR] [QNN] Fix error of reading zero_point during per-channel quantization [tvm]

["MPolaris (via GitHub)" <gi...@apache.org>]

MPolaris opened a new pull request, #16479:

   Quantification is usually divided into two modes: per-channel or per-tensor.
   For per-channel zero_point and scale are 1d array and it's length same as tensor channel.
   For per-tensor zero_point and scale are scalar.
   At present, when using onnx-qnn in the frontend, tvm seems to only consider per-sensor quantization.
   Additionally, for both quantization modes, read zero_point can be used in this way without causing errors.
