MLBEDSW-10106: Improve HLCS featuremap mapping mechanism.

Philip Hall requested to merge MLBEDSW-10106B into main

HLCS generation uses a positional equivalence between tensor index and tensor usage to map ifms from Schedule IR to HLCS. This doesn't scale and required looping over a fixed number of IFMs.

  • Switch from positional to tensor-usage based IFM mappings.
  • Allow potentially unlimited input IFMs for HLCS operators.
  • Improved field layout of HLCFeaturemap to reduce memory wasted by padding.
