Filter aliasing nodes from memory timeline (#4468)

Summary:
Pull Request resolved: https://github.com/pytorch/executorch/pull/4468

Through memory offset view, I noticed that we have a bunch of allocation objects that alias each other. These include:

- "output" nodes
- "aten._view_copy_nop.out" nodes

Making an attempt to filter these out so the visualization is more accurate
