MLBEDSW-5582: MLCE: memory corruption with zero concat

 - This bug was due to an interaction between multiple Ethos-U custom
operators and concatenation of constant tensors
 - It resulted in different parts of the concatenation being placed in
different custom operators
 - The fix involves places all parts of the concatenation into the
same custom operator by switching to a breadth first search in pass
packing
