Enable -Wexit-time-destructors for all in-tree library targets and
update process-lifetime library statics so they no longer register
exit-time destructors. Long-lived caches, lookup tables, singleton
registries, and generated constants now use NeverDestroyed or leaked
references where the data is intended to live until process exit.
Update LibWeb, LibLine, and the binding generators so regenerated
sources follow the same rule instead of reintroducing destructed
statics.
This adds the basic infrastructure for the Permissions API, including
the `Permissions` and `PermissionStatus` interfaces. The API is exposed
via `navigator.permissions` on both `Window` and `WorkerGlobalScope`.
- `is_permission_supported` is hardcoded to return false.
- The `query()` method checks for a secure context but rejects all
queries since no powerful features are supported yet.
The permission store and permission key related methods and algorithms.
Ability for the user agent to store the permissions entries.
Passes a few more subtests in `permissions/`.

This one behaves differently because now the `query` property is
defined. And the last subtest passes for the wrong reason.
"Querying "fullscreen" permission with "allowWithoutGesture" false
is unsupported"
but in fact everything is currently unsupported.
https://wpt.live/fullscreen/api/permission.tentative.https.html
permission is marked as experimental in Navigator and WorkerNavigator,
so tests that now pass actually don't because the tests don't have
access to the interfaces.
