Use Static Arrays for Vertex Buffer Bindings & Attributes

Browse Source 
We cannot statically construct the vertex buffer/attribute arrays for Vulkan due to inactive attributes or buffers which isn't possible on Vulkan, we also cannot just change the count dynamically as there might be disabled buffers or attributes in the middle. We just have a `static_array` which should dynamically be filled in with buffer binding/attribute Vulkan structures before submission.
