feat(builtinlib): move some components from core to builtinlib

[pearmini]

把一些不会不会暴露给用户的组件放入 builtinlib，只供 runtime 使用。

export function builtinlib() {
  return {
    'component.axisRadar': AxisRadar,
    'component.axisLinear': AxisLinear,
    'component.axisArc': AxisArc,
    'component.legendContinuousBlock': LegendContinuousBlock,
    'component.legendContinuousBlockSize': LegendContinuousBlockSize,
    'component.legendContinuousSize': LegendContinuousSize,
    'interaction.event': Event,
    'composition.mark': Mark,
    'shape.label.label': LabelShape,
  } as const;
}
