Description

## 🚀 Feature

This is a sub-issue for the pattern matching feature. To mark this done, the idea is to be able to trace and replace a known pattern from #2693.

This work includes figuring out how `torch.fx.replace_pattern` work and what is needed to use it successfully. Moreover, it includes creating a branch with the needed changes in the `ThunderCompiler`.
