Add `as_ptr_cast_mut` lint

This lint detects calls to a `&self`-taking `as_ptr` method, where the result is then immediately cast to a `*mut T`. Code like this is probably invalid, as that pointer will not have write permissions, and `*mut T` is usually used to write through.

Examples of broken code with this pattern:
