By migrating the debug menu to LibWebView, the AppKit and Qt UIs are now
in sync - the AppKit UI was previously missing some actions.
Further, this inadvertently fixes bugs around applying debug settings to
new web views, especially across site-isolated processes. We were
previously not applying settings appropriately; this now "just works" in
the LibWebView infra.
This migrates all duplicated context menus from the UIs to LibWebView.
The context menu actions are now largely handled directly in LibWebView,
with some UI-specific callbacks added to display e.g. confirmation
dialogs.
Actions that only ever apply to a specific web view are stored on the
ViewImplementation itself. Actions that need to be dynamically applied
to the active web view are stored on the Application.
This removes the old autoplay allowlist file in favor of the new site
setting. We still support the command-line flag to enable autoplay
globally, as this is needed for WPT.
This brings keyboard shortcuts for the inspector up with common
convention in FF and Chrome: Ctrl+Shift+C now also opens the inspector,
and F12, Ctrl+W, and Ctrl+Shift+I now close the inspector when the
inspector window is focused.
Resolves#972
m_hover_label did not have checks if the mouse is in the same location.
This caused clickable URLs to be hidden.
Also shortened the label text to not be longer than half of the window.
