The current behavior for the Node Editor's Add menu is to list the
user's asset catalogs at the root level of the menu. However, an
exception is made if the catalog has the same name as a builtin menu.
In such case, the asset catalog is appended to that builtin menu,
instead of being drawn at the root level.
How this is currently implemented right now is to have a hard-coded set
of builtin menus in `add_menu_assets.cc`. Certain menus are missing from
this set, particularly newer ones, which may be an oversight during the
creation of these menus.
This patch adds those menus to that list, which are as follows:
- Input/Gizmo
- Input/Import
- Grease Pencil (and all its submenus)
- Texture (in Compositor Nodes)
