Customize: Allow page stubs to be created via dropdown-pages controls in the Static Front Page section.

Browse Source 
This ability was previously added to nav menus via the available page items panel. The "Add New Page" button only appears when the `allow_addition` control param is supplied as `true`. Code is adapted from the Customize Posts feature plugin.

Props celloexpressions, westonruter.
See #38013, #34923.
Fixes #38164.
