set_axis_position() potential unused

[classicrocker883]

Description

in module/stepper.cpp
Stepper::set_axis_position() true intentions may be underutilized. it appears to be used only once in planner.cpp for only E_AXIS

So, I removed the call for other Axis' and renamed to set_e_axis_position to indicate its actual purpose.

I suppose this may get rid of the functions "future proofing", however, it is beyond me if this function has another use based on the original purpose.

For now, this change suites it for now.

So why are you submitting a PR? This also doesn't pass CI checks / breaks builds without an extruder.

It makes sense to preserve set_axis_position as a standard method of this class, and for the benefit of forks that may be using it for other things. If E happens to be the only axis that uses it in our fork, the single parameter may be optimized away by the compiler by looking for the invariance. We can help it along by noticing the invariance at compile time and calling set_e_position instead of using the standard method for any axis.
