### Current behavior?

Pointers `this->edge_pad_low_`, `this->edge_pad_high_`, `this->interior_pad_` reference memory locations of size 48 bytes as they point to arrays of int64_t of `kMaxDims` elements, where `kMaxDims == 6`:
https://github.com/tensorflow/tensorflow/blob/bd1c3bf880a103425cfa5dd49ab3d1bf84857d13/tensorflow/lite/kernels/stablehlo_pad.cc#L36
https://github.com/tensorflow/tensorflow/blob/bd1c3bf880a103425cfa5dd49ab3d1bf84857d13/tensorflow/lite/kernels/stablehlo_pad.cc#L221-L224

These pointers are passed as parameters to function 'memcpy' with a size parameter `TFLITE_STABLEHLO_PAD_PARAMS_MAX_DIMENSION_COUNT` * 8 that is always equal to 64 bytes:
https://github.com/tensorflow/tensorflow/blob/bd1c3bf880a103425cfa5dd49ab3d1bf84857d13/tensorflow/lite/kernels/stablehlo_pad.cc#L98-L108

 This can lead to a buffer overflow.

It's worth noting that in [tensorflow/lite/core/api/flatbuffer_conversions_test.cc](https://github.com/tensorflow/tensorflow/blob/b19a54c0d9739f9c548222d625c1413628b3a43f/tensorflow/lite/core/api/flatbuffer_conversions_test.cc)
var `kMaxDims` is explicitly assigned the value of the constant `TFLITE_STABLEHLO_PAD_PARAMS_MAX_DIMENSION_COUNT`:
