Godot: Missing Bool XOR from GDscript
Godot version: 3.0.2
Issue description:
GDscript is missing bool xor.
Steps to reproduce:
If you try:
var one = true
var two = false
var three = one^two
You get an error

There's the cheap solution: var three = one != two.
The xor operator (^) is meant for bitwise operations. I wonder if it could be extended to work as a logical operation as well.

As per the discussion on #22740, adding a xor operator for booleans wouldn't have any practical use as it's the same truth table as the != operator, and it's not a common feature in programming languages to extend it to bools.

xor operator would still be good imo, I actually tried it first before figuring out I could use !=. There's also a slight difference in semantics: "flip if differ" and "not equal", despite the fact that the truth table is the same.
Adding xor operator for booleans can also prevent users to accidentally apply xor/!= operator on integers, throwing parser error in typed GDScript (3.1).
