fix: Use a custom normalize_path to resolve duplicate symbol problem

[phated]

This PR helps to better support rust->wasm compilation of the circom compiler. I believe the wasm target doesn't support std::fs::canonicalize but @antimatter15 can probably provide more context on his change.

This is currently a draft because I want to discuss how we can handle the "file existence" check that std::fs::canonicalize was providing. Is there a better way or place to check for file existence that will work in rust & wasm?

We could probably re-implement it ourselves using other APIs
