Summary:
flipper-server-companion depends on flipper-plugin. flipper-plugin includes dependencies that run only in a browser. Splitting flipper-plugin into core and browser packages helps to avoid including browser-only dependencies into flipper-server bundle.
As a result, bundle size could be cut in half. Subsequently, RSS usage drops as there is twice as less code to process for V8.
Note: it currently breaks external flipper-data-source package. It will be restored in subsequent diffs

Summary: `device.realDevice` was the escape hatch used in Sandy plugins to give access to device specific features like taking screenshots, clearing logs or accessing `adb`. Since in decapitated Flipper that won't be possible anymore (since plugins run in the client but device implementations on the server), all escape hatches have been bridged in this stack, and we can get of the `realDevice` interaction, by explicitly exposing those cases, which makes it type safe as well.
