Andreas Kling c7e24fce2f LibWebView: Persist and restore zoom level per host ...

Remember the zoom level for each host so that returning to a site
restores the zoom the user previously chose, matching what other
browsers have done for years.

When the user zooms in, zooms out, or resets the zoom, the resulting
level is written to Settings keyed by the current page's host. On
navigation, when a view's URL host changes, the stored level for the
new host is applied (or the global default if there is no override).

Per-host zoom changes are broadcast through the SettingsObserver so
that two tabs viewing the same host stay in sync as soon as the user
adjusts zoom in either one. Zoom changes from within the page (such
as internals.setBrowserZoom hook) and the WebContent restart path do
not persist, only user-initiated zoom changes do.
