Transform and Rigidbody(2D) vector extensions

[bas-boop]

Is your feature request related to a problem?
The vector extensions do not work on something like transform.position or rigidbody.velocity. Because they are a temporary value.

Describe the solution you'd like
New functions that can be called from the transform rigidbody(2D) that do all the stuff you want with the vector extensions.

Additional context
Something like this rigidbody.ChangeVelocityX(speed);, source: https://github.com/bas-boop/Smoll_Knight_plus_Horse/blob/Develop/Assets/Scripts/Framework/Extentions/Rigidbody2DExtensions.cs
