Vulkan: Tune pruneEmptyBuffers() to be a bit more aggressive Right now we check every second and if we find a buffer is empty and remains empty for 4 checks, we free the buffer. This means we may keep peak memory usage for 4 seconds. This CL reduces the check to 1/4 seconds, so that a buffer will gets freed if not used for 1 second. Also added a threshold to keep maximum count of empty buffers to 16. This CL also optimizes pruneEmptyBuffers() function to avoid erase calls on each empty buffer block. We set the pointer to null as we free the empty buffer and a new loop is added at the end to remove all null elements at once.
