No constructor for basis as a copy of another basis

[TempusFugit05]

Your Godot version: 4.3.stable

Issue description: There is no actual constructor to create a basis from another basis.

It works in GDScript:

func _ready() -> void:
    var original: Basis = Basis.IDENTITY
    var copy: Basis = Basis(original)

Are you using C#? The equivalent is:

    public override void _Ready()
    {
        Basis original = Basis.Identity;
        Basis copy = original;
    }

The docs should probably note that this constructor is only available in GDScript.
