render/vulkan: Dynamically handle pipeline creation

The current way we handle pipelines is unmanageable as we add more pipeline variants. Instead we should dynamically manage them.

Future work:

1. Do this for pipeline layouts
   • Maybe just create pipeline layouts along with pipelines at risk of creating duplicate layouts
2. Consider lazy initializing pipelines (literally just deletes code)
   • I'm worried that compiling pipelines during draws instead of buffer bind time could be problematic
