Remove canonicalization functionality from VFS and related components

- Eliminated the `canonicalize` method from the `VfsBackend` trait and its implementations in `InMemoryFs`, `NoopBackend`, and `StdBackend`, simplifying the interface and reducing complexity.
- Updated various parts of the codebase to remove references to canonicalization, including tests and prefetch cache handling, ensuring consistency across the project.
- Adjusted logging and comments to reflect the removal of path normalization logic, enhancing clarity and maintainability.

These changes aim to streamline the VFS implementation by focusing on core functionalities without the overhead of path canonicalization.
