Issue with int8/uint8 type for AveragePool and int8 for MaxPool

[nives-vukovic]

In https://github.com/ROCm/AMDMIGraphX/pull/2973, uint8 type has been enabled for MaxPool, however following test cases are failing:

• AveragePool with padding and uint8/int8 type
• AveragePool with stride that is not default (in this case it is equal to 3)
• MaxPool with padding and int8 type

Outputs of verify tests are provided in attachment. log_avgpool_pad_error.txt log_avgpool_stride_int8_error.txt log_maxpool_int8_error.txt
