Add mutex on read/writing m_CulledLights, guarantees it won't be overwritten twice while doing a callback before finishing rendering next frame or would write while allocating lights

Fix baked fog on scenes, only enable volumetric fog if there are any fog volumes in scene https://files.facepunch.com/sampavlovic/1b2511b1/image%20%289%29.png

lb_indexed_pointlight_shadows. By default for now, don't cast shadows to indexed point lights if the cvar is set, rarely worth anything useful

Fix file move on vpc for shadowmap_texturebarrier_renderer.h

Fuck off with subrect clearing on shadowcache, we do it much simpler on draw now which is guaranteed to be clean, our goal is to go bindless too so it doesnt even apply Pass per view lighting constants to shadow, transition barriers to fog

Make CSM to be re-rendered for each view since they are view-dependent, but we can keep the same tiles we reserved Static vs. Dynamic object rendering for FindOrCreateShadowMapsForLight

Remove shadow template views, doesn't make sense to have this code duplicated and makes it harder to work with it, I don't think we use those HLVR constants the code mentions, and if we do it should just be on the standard pipeline Vulkan: Fix ClearImpl not respecting layer viewports smaller than the screen, and instead just clearing everything with a fast renderpass, this caused issues when we want to just clear a small rect lb_time_sliced_shadows, fix directional lights not showing up, clear each rect when wanting to draw rather than having a complicated shadow atlas clear system

Time sliced shadows + shadow caching

Remove ConsiderLight and LightEntry, they're bullshit now and overcomplicated, used to figure out which lights had priority but not needed anymore, data flow is leaner now

Backport more shadowcache code from cs2, start adapting lightbinner for new layout

Reduce parallel cubemap updates on load, we allocate a new lightbinner for each new parallel view and each of them allocates a lot of new GPU buffers when they should be shared, I'll revisit this after shadowcache

Remove all atlas downsampling bullshit, not even being used Backport shadowcache from CS2
