  1. [Impeller] batch up filter graph command buffers. (#51912) 

    The filter graph frequently creates and submits command buffers in serial. This has some unnecessary overhead, esp on Vulkan where submitting a command buffer has a non-trivial cost. While previously I had tried to batch up all submissions, doing this in a limited manner in the filter graph should be more straightforward.

For gaussians this makes a big difference, as there is a mipmap generation, downsample, then 2 render passes, so we can compress the 4 command buffers into 1.
