Add an IndexableText structure for text queries.
Instead of linear search for a node this now uses a HashMap.
Remove the now irrelevant fields from TextDisplayItem.
Include non-upstream metadata changes in WPT sync.
The original sync work excluded changes to metadata files under tests/wpt/mozilla under the assumption that any change in test results indicated an existing intermittent issue. This is incorrect, because these tests rely on shared infrastructure with upstream, so the results can be influenced by syncing.

Add font cache debugging to isolate cause of IPC failures in CI.
This should help us better understand the actual underlying cause of frequent CI failures like #13509. In particular, we will be able to state with confidence whether an IPC message is being dropped while the font cache thread is still alive, or whether the dropped sender was in a message that was in the queue after the font cache thread was shutdown.
