High performance and flicker free behavior on terminal resize

[jacob314]

This requires migrating to RenderStatic for from Static for history items
and updating the history items in small batches on resize rather than attempting to update the entire history the first frame after resize.

RenderWorker changes in Ink will also help mitigating by resolving the current issue where outside of alternate buffer mode, there is a large flicker of previously rendered content on resize.

We have migrated to StaticRenderer and we optimize to only render 1000 chars on the ink side but we haven't yet landed the corresponding optimization to 1000 chars on the Gemini CLI side
