EditorControls: Add duplicate pointer ID fix.

[Mugen87]

Related issue: #27748

Description

Applying the same pointer ID fix from OrbitControls to EditorControls.

@sciecode Given how similar controls handle multi pointer events, I wonder if we could centralize some logic into an upper class Controls (or PointerControls) and then extend from it 🤔 .

Yeah, they do look similar enough that is worth considering it.

There's always an extra effort having to debug things over multiple files & implementation specific behaviour might eventually diverge, but we can give it a try and revert later if it proves more trouble than it is worth.

Will see if I can come up with a draft PR.
