This PR adds support for the optimized Xtensa max and average pool kernels when using 16-bit activations and 8-bit weights. Previously, this configuration would fall back to the reference implementation.

Changes:

  • Created new 'pooling_hifi.cc' file which contains implementations of max and average pooling for both 8-bit and 16-bit inputs
  • Removed old 'pooling_int8.cc' file

bug=fixes #3482
