Subject: feat(mlint): support RenderResult::default and ::from detection

Extend the `unnecessary_render_result_creation` lint to also flag uses
of
`RenderResult::default()` and `RenderResult::from(...)`, and add
`#[derive(Default)]` to `MlintReport` and `MlintLevel` to simplify
struct
instantiation
