babel-cli plugin options (T7426)

Issue originally made by @hax

Description

Currently it seems no way to set options for plugins. Or at least no document.

The majority of Babel plugins that support options have examples documented on our site: https://babeljs.io/docs/plugins/transform-async-to-module-method/#usage for example.

talking about plugin options but through babel-cli options rather than a babelrc I think
