Allow plot_probe not to plot on axes, but just return polycollections

[jakeswann1]

Retains previous default behaviour, but adds the option not to plot the collections on an axis, but just to return them. This is useful for incorporating the probe layout into other plots (such as SpikeInterface widgets).

Hi Jake.
I understand the need but I find the design a bit complicated and the option not super intuitive.
Why not having a clear separated function that create the poly that would used internaly by plot_probe and also by you specific need ?
Maybe it is more changes, I don't known. I will try to have a deeper look

Hi Sam, thanks! That makes a lot of sense, I'll work on a refactor

Hi @samuelgarcia, I think this is ready for review - split into a new function as suggested
