DOC: document optional arguments on plot submethods

[shoyer]

As a follow up on #9321:

We should start adding optional arguments that are common between multiple plot types to the signatures for plotting sub-methods, such as figsize and axis. Currently, these are only documented on the main .plot() methods and we use **kwargs for the rest. This would be nice because we could clarify for users which optional arguments work for which types of plots -- this is not at all obvious right now.

@JanSchulz suggests we could perhaps do this dynamically by updating the __signature__ object. However, I don't know yet if this will generate the correct API documentation -- maybe if Sphinx is run using Python 3?
