breaking: Rename render context APIs to layer context

• getRenderContext() → getLayerContext()
• setRenderContext() → setLayerContext()
• supportedContexts prop → layers prop on components
• Internal layout/ directory moved to layers/ (affects deep imports)

- import { getRenderContext } from 'layerchart'
+ import { getLayerContext } from 'layerchart'
