[Feature Request] Add Vector2 and Vector3 etc. static class with const string to improve usage in switch expression

### Type of issue

Other (describe below)

### Description

Reading the System.Numerics docs of the Vectors 2+3 I did see there are Fields typed to int, but I would miss there a static class with const string to use them in a switch expression from the with net9.0 available lang features of C#

Currently I defined them locally with:

```csharp
public static class VectorNames
{
public const string X = "X";
public const string Y = "Y";
public const string Z = "Z";
public const string W = "W";
}
```

but it would be great, if those would be already build in in same Namespace 🚀
