Fixes https://github.com/flutter/flutter/issues/153335 When platform views are present, we always repaint entire frame. We must pass the buffer damage all the way to `GPUSurfaceMetalSkia/GPUSurfaceMetalImpeller` so that they know that the other two surfaces are lagging behind front surface and need to be repainted. This is currently not being done with platform view present, that's why we miss full frame repaint when removing platform view. With this merged in, it should be safe to reland https://github.com/flutter/engine/pull/54537 without any changes.
