Allow to select multiple remote nodes at runtime

[YeldhamDev]

Closes #93628.

Screencast_20241125_111648.webm

Features Implemented

• Multi selection of multiple nodes, even if from different types. The properties shown in the inspector will be the ones shared by all the ones selected, like how MultiNodeEdit works.
• Region selection for Node2D/Control and Node3D nodes.
• Additive selection: holding Shift will add/remove items to the selection group instead of overriding it.

I want some feedback on how to handle limiting selection of too many nodes, because that carries the risk of encoding of the data failing and no selection occurring.

• What the default limit should be? 10-ish or so?
• Should it be a hard limit, not allowing to select further nodes? Or a soft one, only printing a warning when the limit is exceeded?

[KoBeWi]

Maybe hard limit with warning?
How many nodes can be selected before it breaks?

[YeldhamDev]

@KoBeWi Missed your message, sorry.

It depends on the data size of the objects. On my end for example, selecting more than 30 Button nodes starts to break things.

[KoBeWi]

So limit it to 20-25, if someone tries to select more nodes pop a warning toaster. The limit can be configurable in editor settings. Personally I rarely select more than 5 nodes; most often it's to move them in the scene, which is not something you can do in Remote tree.

[YeldhamDev]

The selection limit has been implemented.

@AeioMuch Should be fixed now.

@AeioMuch Should be fixed now.

It works fine now 👍, but there's is still a small issue remaining : while using the drop down menu of recently edited object will properly reselect the correct node(s) in the remote scene tree, using the backward and forward arrows will not reselect them, only update the inspector.

@AeioMuch Try again.
