BUG: plot drag curves when function source is callable

[Gui-FernandesBR]

Pull request type

• Code changes (bugfix, features)

Checklist

• Tests for the changes have been added (if needed) (no idea on how to do that smartly)
• Docs have been reviewed and added / updated
• Lint (black rocketpy/ tests/) has passed locally

• CHANGELOG.md has been updated (if relevant)

Current behavior

When you use a callable object as the source of your power_on or power_off curves in the Rocket class, the all_info() method will break because self.rocket.power_on_drag.x_array is inexistent

New behavior

Solved the issue by adding a try/except block that will prevent code from breaking in the situation

Could you also fix this line?

RocketPy/rocketpy/prints/aero_surface_prints.py

Line 138 in b0e34e9

f"Number of points defining the lift curve: {len(self.aero_surface.airfoil_cl.x_array)}"

The airfoil prints will run into the same bug if it is callable defined

This is a very good comment. Let's fix it in another PR.

I think it's important to add a test to this PR so we prevent the same error from happening again in the future
