This replaces the direct shader uniform layout declaration by a linear search through a global buffer. Each instance has an attribute offset inside the global buffer and an attribute count. This removes any padding and tighly pack all uniform attributes inside a single buffer. This would also remove the limit of 8 attribute but it is kept because of compatibility with the old system that is still used by the old draw manager.
