adding to the default Maya menu overwrites the whole menu

When you add a menu item to a default Maya menu (e.g. Windows, Mesh, File, …) on startup, it overwrites the whole menu.

There’s a partial fix that works for some menus.
Run this before adding to the Maya menu to avoid overwriting the whole menu.
but this only supports strign commands. no callables.

# As Maya builds its menus dynamically upon being accessed,
# we force its build here prior to adding our entry using it's
# native mel function call.
mel.eval("evalDeferred buildFileMenu")

# use maya.utils.executeDeferred for callables
# or use maya.cmds.evalDeferred for strings
maya.utils.executeDeferred(add_to_menu) 

depending which menu, run a different build command

Pyblish Maya handles this
adding itself to the File menu, but the same doesn’t work for the window
