Vulkan: Update a test to triger large dirty bit handling Some traces bind one VBO to a large number of VAOs,and use glBufferData to change buffer size frequently,this will cause glBufferData spending a lot of time doing VAO dirty bit handling, which leads to high cpu load in these traces.This test could triger this issue.
