rCOMM2d33aa44aaf5: [native] Lift `renderSearch` to `ConnectedChatThreadList`

Summary

This diff is just one step in the process of converting ChatThreadList into a functional component. When this work is done, we will be able to avoid a lot of re-rendering and hopefully improve performance quite a bit.

NOTE: There's a lot that can be refactored/improved/optimized. This is just to make progress on converting class component to functional component.

Depends on D9164

Test Plan

ChatThreadList + search experience continue to work as expected.

Also as I side note, I wonder if upgrading our animation code here to renanimated 2 or 3 api would improve performance. I know that renanimated 2-3 was built with functional components first in mind and IIRC the newer apis have a bunch of hooks to create animations in a more performant way

I agree that it would be good to migrate away from the Reanimated 1 API... given it's deprecated in Reanimated 3, we'll eventually need to migrate there anyways. Looking at animateTowards though, it seems fairly complicated... I don't think it makes sense to block @atul's work here on transforming that to the new Reanimated API. We'll probably need to have the Reanimated conversion be a monthly goal for someone...

I know GPT is good at "translating" code from one language to another. It might be helpful for "translating" from Reanimated 1 -> 3? Obviously someone who understands Reanimated well would need to take a careful look to make sure things are correct, but might be a helpful tool that could speed things up.

That makes sense. I created this linear task to track this migration project

132–133	The props will be removed altogether in a few diffs so I think it's fine for now.
299–301	It is in subsequent diff w/ some of the search-related functions
559	Yeah it'll happen once `flatList` is moved out of the class component and we have a ref
