[renderer] Support multiple entity queues While there's currently only the one still, this will allow the entities to be multiply queued for multi-pass rendering (eg, shadows). As the avoidance of putting an entity in the same queue more than once relies on the entity id, all entities now come from the scene (which is stored in cl_world in the client code for nq and qw), thus the extensive changes in the clients.

[vulkan] Load the map's lights into an array It's not used yet as work needs to be done to better support generic entities, but this is the next step to real-time lighting (though, to be honest, I expect it will be too slow to be usable).

[vulkan] Implement the sprite render passes It turned out the bindless approach wouldn't work too well for my design of the sprite objects, but I don't think that's a big issue at this stage (and it seems bindless is causing problems for brush/alias rendering via renderdoc and on my versa pro). However, I have figured out how to make effective use of descriptor sets (finally :P). The actual normal still needs checking, but the sprites are currently unlit so not an issue at this stage.

[renderer] Make R_RenderView private This is actually a better solution to the renderer directly accessing client code than provided by 7e078c7f9c8ab27af92ff268f49bac070c9ff617. Essentially, V_RenderView should not have been calling R_RenderView, and CL_UpdateScreen should have been calling V_RenderView directly. The issue was that the renderers expected the world entity model to be valid at all times. Now, R_RenderView checks the world entity model's validity and immediately bails if it is not, and R_ClearState (which is called whenever the client disconnects and thus no longer has a world to render) clears the world entity model. Thus R_RenderView can (and is) now called unconditionally from within the renderer, simplifying renderer-specific variants.

[particles] Merge particle spawning into client After yesterday's crazy marathon editing all the particles files, and starting to do another big change to them today, I realized that I really do need to merge them down. All the actual spawning is now in the client library (though particle insertion will need to be moved). GLSL particle rendering is semi-broken in that it now does only points (until I come up with a way to select between points and quads (probably a context object, which I need anyway for Vulkan)).
