Jonah Williams d58cd98b8c [Impeller] Add keep alive for 4 frames in render target cache. (flutter/engine#57020)
Improve cache usage by keeping textures alive for 4 frames after the last usage. This improves cache usage in scenarios such as repeatidly dragging the android overscroll functionality.

THis isn't expected to have a negative impact on memory, because a texture cannot be _immediately_ deleted anyway.
