Follow-up to https://webkit.org/b/225972

In the Styles details sidebar panel, an unused inherited variable is shown if found in the value of a declared but unused variable on the matching styles.


```
div {
  --never-used: var(--never-used-inherited);
}

html {
  --never-used-inherited: red;
}
```

Expected:
`--never-used-inherited` from inherited styles should be hidden because it is not _actually used_.
