Restore Plugin HTML After a WebKit Reload

Plugin dialog content is injected with SetPage, so on the WebKit backends a
reload (context menu, keyboard shortcut or location.reload()) re-fetches the
SetPage base URL instead of the injected document, and the plugin UI is gone
for good: load_plugin_content() returned early once m_content_loaded was set.

On GTK and macOS, re-inject the plugin HTML when a main-frame load arrives
after the initial swap. m_own_page_load marks the load caused by our own
SetPage so it is not mistaken for a reload, and a post-load error is left
alone, as it only ever means a failed subresource.

MSW is left out: WebView2 reloads NavigateToString content from its own
history entry, so the page already survives a reload there, and the backend
reports in-document navigation (a page setting location.hash) as a load,
which re-injection would turn into a page wipe.
