Issue description

Since #87623 has been merged the alt key is used as a drag-and-drop modifier to instantiate scenes as a child of root instead of a child of a selected node. However, this now conflicts with none default navigation schemes.

Steps to reproduce

Change navigation scheme to Maya or Modo.

Hold Alt while doing drag-and-drop to instantiate scene as a child of root

What modifier should we use instead when using the Maya or Modo navigation schemes? Shift is already used, and Ctrl should be avoided as it's used for the grid snapping toggle.

[ryevdokimov]

Maybe just have the drag-and-drop override the alt functionality in the viewport? This seems to already be the case with right-click functionality, which prevents orbiting.

[ryevdokimov]

I think there is some kind of conflict with right-click as well now that I'm looking into this again. IMO I think it's just better to disable freelook, navigation and/or all input all together when drag-and-dropping.

I don't see how the modifiers are conflicting if you need to hold them only on release. So position your node and then hold Alt while releasing the mouse button.

[ryevdokimov]

I suppose that people can train themselves to do that, but I don't think it's ideal. I'm personally used to preemptively selecting and holding the modifier keys as I drag especially when doing multiple scenes, otherwise I'll have to do some finger dancing.
