CopyStream: Change way the cmdBuffer is recorded
Before, keep submiting a lots of command buffer to emulate the
glBufferSubData in glbench, which adds lots of CPU overhead and not
ideal for vulkan benchmark.
Instead, We try to record multiple copy command in one single command
buffer and submit it. Also adds specific fences and remove unneeded
calls, e.g. draw calls.
- Move Setup/Destroy function out of the time measurement.
- Add RunFunc function
- copy.BufferStream now records commandbuffer that tries to copy the
buffer into another buffer segment by segment.
