Currently in Rust, kunit tests are handled with `kunit_tests`, while the doctests generate a lot `extern "C"` functions and invoke them through a generated C wrapper.
This is currently needed because of the special treatment of file name and line numbers from doctests. Convert them to override `file!()` and `line!()` macro instead, and use them inside `kunit_assert!`. With this it is possible to just generate `#[kunit_tests]` and `#[test]` for doctests. David mentioned in [1] that this should route via the Rust tree.
