Moved tiled rendering buffers to lightbinner, where it should belong
Remove members that have long been deprecated, start adding support for structured buffer lights
Move all cbuffer stuff to legacy, standard will only have structured buffer path
Start implementing structured buffer lights data structure
Remove all code for calculating mixed shadows, that'll be all allocated in the main light shadow function, iterate structured buffers
Iterate on new lightbinner, let all shadows render through a single rendering path, disregard legacy for now
Remove bMixed from LightEntry, it's complete bullshit, let static lights render only dynamic objects when doing shadows
Unified shadow casting, map indexed lights so we can fetch them easily and without needing to order sequentially, remove more deprecated stuff
Get rid of lightbinner_legacy completely
Eliminate legacy per view lighting constants, eliminate mixed shadows, add placeholder to some constants where they should belong
Cut more code from lightbinner light allocs, means only spots will alloc properly for now but cleans a lot of this, align cbuffers, add ComputeDirectLightingForLight to unify lighting calculation on shader
Remove CSunLightManager, used for old pre-hlvr sun rendering, a lot of code that's only used for dynamic sunlight different to everything else in light rendering
Remove more unused parameters from lightbinner
Remove remaining crumbs of old sun shadowing, remove unused shadow functions, add bBaked to ComputeDirectLightingForLight
Lightcookies and point lights
Remove multiview constants from lightbinner, these have been getting in my way, and we need to think a better way to handle instanced viewports, I'm leaving it to a bigger cleanup later
Start Envmap support on new lightbinner, remove unused environment_map.fxc
Start MATERIAL_LIGHT_DIRECTIONAL support for lightbinner, sets up frusta for lights
Fix conflicts from merge that added removed stuff
