The name was confusing as this signal is emitted around the same time as
`tree_exiting` and `NOTIFICATION_EXIT_TREE`, i.e. while the child node is
still in tree.
Fixes#59210.

Exposes the "interpolated" flag on nodes via a property, physics_interpolation_mode.
Mode can be INHERIT, OFF and ON. This makes it easy to turn off interpolation for nodes in the editor, versus via code. - lawnjelly
