Standardize logging and error handling

- Introduce new types: LoggedResult and LoggedError
- Introduce new extension methods to log and add additional msgs
- Never exit when logging error messages in Rust (all errors should be
  handled by using Result and Rust's error propagation)
- Remove all usages of anyhow as it doesn't fit Magisk's use cases
