Vulkan:Update Vulkan Vertex Attribute Offsets

This fixes most of the test for dEQP 3.1 KHR-GLES31.core.vertex_attrib_binding.basic-input* The bug fixes is that we were not correctly setting the vertex attribute offset for vertex attribs that were converted into their own buffer. We kept the attrib offset from the frontend as if the converted attribs were in the original buffer, but converted vtx attrib buffers in the VK backend are tightly packed from the start of the buffer so when converting the actual offset should be 0. Also, in order to avoid a VK validation error, this change includes a tmp workaround to make sure transform feedback output buffer range is never 0, but sets VK_WHOLE_SIZE in that case. A follow-on fix that focuses on transform feedback fixes will address this validation error more fully.
