Rollup merge of #85963 - m-ou-se:constructor-type-name, r=yaahc

Browse source 
Show `::{{constructor}}` in std::any::type_name().

Fix #84666

Before:
```
[src/main.rs:6] type_name::<T>() = "playground::Velocity"
[src/main.rs:6] type_name::<T>() = "playground::Velocity"
```

After:
```
[src/main.rs:6] type_name::<T>() = "scratchpad::Velocity::{{constructor}}"
[src/main.rs:6] type_name::<T>() = "scratchpad::Velocity"
```
