* Rework vertex attribute binding for vulkan. Allows always providing a buffer view to the pipeline even if the game has the attribute disabled as long as it is consumed by the vertex shader.
- Improvements to framebuffer usage; Avoid creating new resources every frame
- Handle null fragment program properly
- Collect vertex upload statistics
- vk: Pre-initialize 'unused' varying registers in the vertex shader in case it gets matched with a fs that consumes it
-- Fixes a crash about fog_c not being declared
gl/dx12/vk: Handle null fragment program
- cleanup - use yield semantic instead of sleep(0) as yield is more cross-platform
-- sleep(0) is a windows specific scheduler hint
* vk: fix separate front and back lighting
* vk: Inlined arrays can have emulated primitives too!
* vk: Use float input attribs for better compatibility
* vk: Free resources during shutdown
* vk: separate specular color
rsx: separate front color output from back color output
re-enable front-back diffuse lighting
vk: fix front face selection and actually enable face culling
* dx12: Hide constant-key blended visuals (by common use of factor, 1-factor)
* dx12: Fix 2 sided lighting when the shader does not compute both outputs
* vk/dx12: confirm that src register exists before copying for 2-sided lighting
* gl/vk/dx12: Fix vertex shader code generation for buggy games
dx12: revert vsh attribute changes
* vk: dynamically flush command buffers if we exceed available resources
* dx12: do not prepare flip texture if it has not been initialized
