script: Measure heap usage of various ignored fields (#38791)

Browse source 
These changes allow using MallocSizeOf/`#[conditional_malloc_size_of]`
on WebIDL callback values, and then fix a grab bag of places in the
script crate that previously ignored those values. There are also some
commits removing ignored fields that involved Arc/Rc that are not WebIDL
callbacks, since they are now easier to support with the
`#[conditional_malloc_size_of]` attribute.

Testing: Manual testing on about:memory for servo.org.
