[JTC] Add Parameter to Toggle State Setting on Activation (backport #1231)

[mergify]

This pull request introduces a new parameter in the JointTrajectoryController that enables toggling whether the last command interface value should be set as both the current_state and last_commanded_state upon activation.

Motivation

Consider a scenario where there is a transition from a JTC to another controller and back to a JTC. Due to the implementation specifics of the intermediary controller, it is possible that the command interface values from the first JTC remain. This can lead to dangerous situations where, upon reactivation, the second JTC inadvertently uses these stale command values to command the hardware.

To mitigate this risk, I have added an option within the JTC that ensures command values are reliably reset to reflect the current state upon activation, enhancing system safety.

@bmagyar any idea why the ABI check for iron did not complain, but here it does? Is this a reason to not merge this?
