fonts: Clean up messaging during web fonts loads (#32332)

Browse source 
Instead of sending a message to the script thread via IPC when a web
font loads and then sending another, just give the `FontContext` a
callback that send a single message to the script thread. This moves all
the cache invalidation internally into `FontContext` as well.

Additionally, the unused LayoutControlMessage::ExitNow enum variant is
removed.
