perf(core): test perf of skipping some lifecycle hooks for perf

[JoviDeCroock]

The main thinking behind this is that we are accessing the _component megamorphic object less resulting in better performance.

This leaves four accessors behind

• contextType - our provider is a functional component
• shouldComponentUpdate - our provider component uses this
• componentWillUnmount - our provider component uses this
• componentDidUpdate - this is used in the useState hook
