Jonah Williams b85e2d9b8d [Impeller] CommandPoolVK recycles command buffers too. (flutter/engine#50468) ...

Its a bit ambiguous whether or not resetting a cmd pool returns the cmd buffers resources back to the pool in a way that can be reused on subsequent frames. Since reseting the pool resets the cmd buffers to their initial state, they are safe to reuse once reset. Additionally, through profiling I can observe that there is less allocation in cmd buffer creation when the buffers themselves are recycled, at least on the Mali drivers.
