Exception to `struct_field_names`

Summary

I propose that the clippy::struct_field_names lint, which checks for struct fields whose names share words with the struct's name, check the type name of the struct field—and forego emitting the lint if the field name matches its type (especially from a different scope).

Lint Name

struct_field_names

Reproducer

Some motivating examples:

pub struct App {
    app: widgetui::App, // field name starts with the struct's name
    // ...
}

pub struct Client {
    http_client: reqwest::Client, // field name ends with the struct's name
    // ...
}

Locate the implementation and tests for the clippy::struct_field_names lint, then read how it currently compares struct and field names. Add coverage for fields whose names match their types, including types from another scope, and verify that the lint is not emitted for those cases.
