Llama 3.2 1B - Add specific op tests

[nvukobratTT]

Summary

To confirm that each op individually works for the Llama model, let's add a set of op tests that are specific to this variation of the Llama model.

To do so, here are a few hints:

1. Print unique ops appearing in Llama.
   • To do so, use this feature
2. For each unique op (and related input shape, attribute, etc.) create an e2e op test
   • The recommendation is to keep these model-related op tests as part of the model directory. E.g. forge/test/mlir/llama/ops/*
3. Make sure to run e2e tests as further as possible
   • To make this possible, you can use compile depth (e.g. compiler_cfg.compile_depth = forge.CompileDepth.SPLIT_GRAPH)

Additional info for each of the ops that doesnt work:

• add - eltwise binary broadcast not working
• concat - Tile padding along concated dim 3 not supported yet
• sin i cos - waiting MLIR uplift
• embedding - reshape in TILE_LAYOUT
• matmul - doesn’t meet the required pcc score
• multiply - eltwise binary broadcast not working
• reduce_avg - doesn’t meet the required pcc score
• reshape - reshape in TILE_LAYOUT and if dim != 4 is not working
• transpose - seg-fault (double free)
