aa1f9a1b - [xnnpack][lite-int][graph-build] torchscript -> xnnpack graph (#87824)

[xnnpack][lite-int][graph-build] torchscript -> xnnpack graph (#87824) This point we perform conversion for Torchscript IR to XNNPack graph. Currently we only support converting Add Nodes and fp32 tensor values. As a caveat, we are not building this at runtime. So for testing we just run the xnn graph once ahead of time and with sample inputs and forward it to execute. This is only for testing, and will be changed in a later diff. This will allow us to check that graph creation is sound.
