MLBEDSW-10894: Add a perf_debug_conn table to debug database

Johan Gunnarsson requested to merge MLBEDSW-10894 into main

The table describes connectivity between ops in Scheduler IR. Each row describes one input of an op. It contains 3 fields:

  • id: The scheduler IR operation ID.
  • input_op_id: The scheduler IR operation ID of a node producing an input.
  • input_index: The IFM index that is consuming this input.

Two special values are used to describe graph inputs and graph outputs. "-2" is used in this "id" field for graph outputs. "-1" is used in the "input_op_id" field for graph inputs.

A network that looks like this...

[T1] -> (A) -> [T2] -> (B) -> [T3]

...where T1, T2, T3 are tensors, T1 is graph input, T3 is graph output, A (ID 0), B (ID 1) are operations, will have a perf_debug_conn table that looks like this:

id, input_op_id, input_index 0, -1, 0 1, 0, 0 -2, 1, 0
