breaking(BrushContext|TransformContext): Rename bind:brushContext / bind:transformContext to bind:state

Both BrushContext and TransformContext now use bind:state instead of their previous named bindings. Additionally, properties on ChartState have been renamed:

• chartContext.brushContext → chartContext.brushState
• chartContext.transformContext → chartContext.transformState

- <BrushContext bind:brushContext>
+ <BrushContext bind:state>

- <TransformContext bind:transformContext>
+ <TransformContext bind:state>
