Turbo: data aggregator

[scottrippey]

What

This "data aggregator" approach is to replace the Context-based approach currently used by the Turbo refactor.

The problem

Victory components can be nested inside a parent container:

<VictoryChart>
  <VictoryLine data={data} />
  <VictoryBar data={data} />
  <VictoryScatter data={data} />
</VictoryChart>

The parent container, in this example, needs to aggregate all the data from the children, to determine the range, domain, scale, etc.

In the current Turbo refactor, we did this via Context; each child reports its data to the parent. This happens in a useLayoutEffect, which suffers from major drawbacks -- primarily that it breaks SSR support.

The "Data Aggregator" Approach

This approach is derived from Victory's pre-Turbo behavior. When a parent is rendered, it will actually traverse the children and aggregate all data before rendering.
This works with SSR, and prevents unneeded rerendering.

This also gives us a chance to normalize the data, and provide a simple API for accessing "normalized" data.

@scottrippey Do we have additional work to do here?

[scottrippey]

@carbonrobot This PoC is complete. The approach worked great, but this only applies to the turbo refactor. I suggest we get this merged, as it vastly improves the turbo codebase. Then we can decide what to do with it along with the rest of turbo.

Could you update and sync the pnpm merge conflict?
