Tim van der Lippe 6a0f9d1bcb Define conditional_malloc_size_of for all Rc (#39660)
This updates all Rc that were ignored for malloc_size_of to use
conditional_malloc_size_of, unless the type in the Rc itself doesn't
support malloc_size.

Regular expressions used to search for all occurrences:

```
ignore_malloc_size_of = "Rc.*"
ignore_malloc_size_of = "Arc.*"
```

There are a couple left since they have nested Rc, which I don't know
how to fix.

To be able to define these, several new implementations were added to
`malloc_size_of/lib.rs` as well as
`HashMapTracedValues`.

Testing: if it compiles, it's safe
