Reasoning: Most missing math commands are implemented with #7258. The `meval` crate itself declares that it doesn't strive to stringent standards (https://docs.rs/meval/latest/meval/#related-projects). For example no particular special casing or transformations are performed to ensure numerical stability. It uses the same rust `std` library functions we use or have access to (and `f64`). While the command call syntax in nushell may be a bit more verbose, having a single source of truth and common commands is beneficial. Furthermore the `math` commands can themselves implement broadcasting over lists (or table columns). Closes #7073 Removed dependencies: - `meval` - `nom 1.2.4` (duplicate) User-Facing Changes: Scripts using `math eval` will break. We remove a further `eval` like behavior to get results through runtime evaluation (albeit limited in scope) Tests: - Updated tests that internally used `math eval`. - Removed one test that primarily used `math eval` to obtain a result from `str join`
