[Text Extraction] Ignore transparent (or nearly-transparent) elements when extracting text
https://bugs.webkit.org/show_bug.cgi?id=270598
rdar://124102506
Reviewed by Megan Gardner and Abrar Rahman Protyasha.
When extracting visible text, ignore subtrees where the renderer is transparent (or nearly
transparent). To do this, we adjust `extractItemData` to return an enum (`SkipExtraction`)
indicating whether we should skip text extraction for just the current node, or for the entire
subtree; we then use this to skip subtrees where there is either no renderer (i.e. `display: none;`)
or the opacity is near 0.
