[Feature]: Implement local offset in Inverse Kinematics #2332

Description

@alexis779

What feature or enhancement are you proposing?

IK currently does not let you target the TCP, Tool Center Point, of the robotic arm, just the link origin.

Motivation

As a industrial automation engineer using a robotic arm,
I want to have flexibility on my target position
Because i want to position a link offset on my object, not the link itself. It would collide otherwise. I don't want to add a constraint on the orientation of the link, just a relative position. This generally applies to the link at the bottom of the kinematic chain.

Potential Benefit

It improves Motion Planning performance and overall task speed. It avoids a. adding a constraint on the link orientation and b. going through an intermediate pre-grasp position.

What is the expected outcome of the implementation work?
