Editor: Fix Ctrl+Click on enum values ​​does nothing

[dalexeev]

• Fixes Ctrl-Click on enum value/member does nothing #101089.

This doesn't work across preloaded scripts. It jumps to the right line but not to the right file.

# a.gd
enum Test {
    E1,
    E2,
}

# b.gd
const A := preload("a.gd")

func _init():
    A.Test.E1 # Looking up E1 here doesn't jump to a.gd
