[vulkan] Implement lighting and compose passes Lighting doesn't actually do lights yet, but it's producing pixels. Translucent seems to be working (2d draw uses it), and compose seems to be working.

[vulkan] Implement deferred lighting for dlights Static lights are yet to come (so the screen is black most of the time), but dynamic lights work very nicely (and look very good) despite the falloff being incorrect.

[vulkan] Implement light styles Other than dealing with shader data alignment issues, that went well :). Nicely, the implementation gets the explicit scaling out of the shader, and allows for a directional flag.

// A fat PVS of leafs visible from visible leafs so hidden lights can
// illuminate the leafs visible to the player
[model] Remove 64k limit on visible leafs Modern maps can have many more leafs (eg, ad_tears has 98983 leafs). Using set_t makes dynamic leaf counts easy to support and the code much easier to read (though set_is_member and the iterators are a little slower). The main thing to watch out for is the novis set and the set returned by Mod_LeafPVS never shrink, and may have excess elements (ie, indicate that nonexistent leafs are visible).
