Introduce Maxwell 3D interconnect active state
Active state encapsulates all state that isn't part of a pipeline and can be set dynamically with Vulkan calls. This includes both dynamic state like stencil faces, and command buffer state like vertex buffer bindings. Simililarly to the last commit, the main goal of this is to reduce the number of redundant work done per draw by employing dirty state as much as possible. Without using dirty state for this every active state operation would need to be performed every draw, which gets very expensive when things like buffer lookups end up being reqiored. Code has also been heavily cleaned up as is described in the previous commit.
