(Minor optimization) Matrix4x4::CreateTranslation Vector3 -> 3xFloat

[FrozenKiwi]

Title says it all.

Minor optimization:

public static Matrix4x4 CreateTranslation(Vector3 position) should forward to
public static Matrix4x4 CreateTranslation(float float float)

Doing it that way around avoids the allocation of a new Vector3. This may be handled by the compiler, I don't know - but just in case it's good to avoid allocations.
