Add support for alpha, linewidths and edgecolors to agent_portrayal

[quaquel]

This closes #2341 and adds support for alpha, linewidths and edgecolors as possible values in agent_portrayal. I also did it in such a way that you can either do it at the level of the individual agent or as an overall space_drawing_kwargs argument but get a value error if you do both.

In addition, I updated the tests and solved a few subtle bugs in draw_space related to the match statement.

It would be great to get this in for MESA 3, because the bug is rather subtle due to the complicated class structure in old-style grids.

Looks good, awesome! Maybe copy some of the examples from #2341 to this PR description.

(let's give a bit of time for others to review)
