Swizzle property z and w for int2/float2 and w for int3/float3

[Thaina]

Please add complete swizzle property to int2 float2 int3 float3 similar to int4 and float4 and define it as 0

So that we could simply upcast vec2 and vec3 to another dimension easily as downcast vec4 to lower dimension

Such as

var screenPoint = new float2(5,3);
var groundPoint = screenPoint.xzy; // (5,0,3)
var wallPoint = screenPoint.zyx; // (0,3,5)

Alternatively it might be xy0 x0y _0xy yx0 y0x _0yx and maybe xy1 x1y _1xy yx1 y1x _1yx and so on for specific default number

+1, the number of time i wished there was a way to make point.x0z is beyond count!

I was like, ah yes, lets use assembly definition references to add this...

public partial struct float2
{
	/// <summary>Swizzles the vector.</summary>
	[System.ComponentModel.EditorBrowsable(System.ComponentModel.EditorBrowsableState.Never)]
	public float3 xy0
	{
		[MethodImpl(MethodImplOptions.AggressiveInlining)]
		get => new(x, y, 0);
	}
}

But nope, as soon as it ends up in Bursted code... Burst error BC0102: Unexpected internal compiler error while processing function

At least new float3(float2, z) exists.

Unfortunately, unity is apparently working on enabling users to extend native class, using the attribute [ExtensionsOfNativeClass], but is definitely not supported at the moment.
In the meantime, You can do a pull request and implement it in this file : https://github.com/LTMX/Unity.mathx/blob/master/Runtime/mathx.floatx.gen.cs
Have a nice day fellow !
