This patch adds the workaround for the Vulkan SPEC issue in the T2T copies with compressed formats when the parameter "extent" fitting in one subresource but not fitting in another. You can get the detail of the issue through the following link: https://github.com/KhronosGroup/Vulkan-Docs/issues/1005 This patch implements the workaround for this issue by splitting the affected T2T copy into a T2B and a B2T copy with an internal buffer.
