Formatter breaks up xor assignment operator

Issue description

The formatter will add a space in between the ^ and = in the xor assignment operator.
This:

var num = 4
num ^= 20

turns into this:

var num = 4
num^ = 20

This is invalid gdscript and so breaks compilation.

Steps to reproduce

Use the xor assignment operator anywhere and then format the document.

More examples that bit me this week:

var poweroftwo = 2 ** 4
# Results in the following, which breaks the compiler
# var poweroftwo = 2 * * 4

var inversion = 2 * -1
# Results in the following which is a preference issue alone
# var inversion = 2 * - 1

I believe the fix for this was already published, but I just added some extra tests to cover this.
