vk_graphics_pipeline: Manage primitive topology as fixed state

Browse source 
Vulkan has requirements for primitive topologies that don't play nicely
with yuzu's. Since it's only 4 bits, we can move it to fixed state
without changing the size of the pipeline key.

- Fixes a regression on recent Nvidia drivers on Fire Emblem: Three
  Houses.
