Page IDs were allocated independently by each WebContent PageHost, starting at zero for every process. That made them unsuitable as a global identity for page-presenting compositor contexts, because the same numeric page ID could exist in multiple WebContent processes. Move page ID allocation to WebView::Application and initialize each WebContent process with its browser-assigned first page ID over IPC. New view requests now get a browser-assigned page ID before WebContent creates the PageClient, and PageHost no longer owns a local page counter. This gives page-presenting compositor contexts a stable global page identity, which will allow their context IDs to be derived from page IDs and simplify compositor context allocation in a follow-up.
