Reducing the boundary of rerender of virtual lists. Previously with prop: "strictMode={true}" the VirtualizedList still re rendered each CellRenderer component. Because method getDerivedStateFromProps generated every time a new uniq state and the cells didn’t have a PureComponent. It helps to improve react performance for lists which have 5+ elements.
I reused recomended approach from react doc https://legacy.reactjs.org/blog/2018/06/07/you-probably-dont-need-derived-state.html#what-about-memoization

Noticed that when scrolling VirtualizedList's CellRenderer was re-rendering due to `onCellFocusCapture` not having a stable identify. Change the interface to CellRenderer to pass in the `cellKey` in the callback to save on creating new callbacks.

We're deprecating the unsafe `$Shape` and moving to the safe `Partial`: https://fb.workplace.com/groups/flowlang/posts/1251655088773485
I have previously codemodded all locations that do not cause errors. Now start on the remaining ones: codemod and suppress.

CellRendererComponent can be given a more useful description, and more constrained type, to ensure it is used more correctly.

This change reverts D41745930 (https://github.com/facebook/react-native/commit/2e3dbe9c2fbff52448e2d5a7c1e4c96b1016cf25) as part of a stack to splice back source history which was lost (Git registered the file moves as additions).
It is expected this diff will individually fail. The entire stack should be applied at once.
