[Vulkan1.2] (Proof of Concept) Implement Bindless Rendering

[thr3343]

Not the final PR

• Contains alot of broken test code + other merged PRs unrelated to Bindless Rendering
• Will replace with a new PR without the unnecessary commits, once its more complete + finalized

This PR is a proof of concept that implements a special rendering system called Bindless rendering, which gives the following enhancements

Added Enhancements/Features

• Reduced pipeline complexity + pipeline boilerplate

  • Reduces reliance on shader .jsons
  • Pipeline layout is global and shared between all pipelines
  • DescriptorSetLayout is also global: Allows Descriptor updates and binds to be optimized down to once per frame

• Bindless Textures

  • Textures are stored in a Descriptor Array
  • Improves speed + CPU overhead of texture switching
  • Entity + Text rendering performance is enhanced when handling complex environments
    • e.g. Texture heavy scenes like Entities, Text, Nametags and Player rendering
  • Image transitions greatly reduced
  • Supports Max limit of 65536 textures for Modpacks

• Bindless Uniforms

  • UBO usage reduced to 1KB to fit in GPU L1 cache
  • Uploads greatly reduced

• Shader optimizations

  • Some Uniforms optimized to Push Constants
  • Inline Uniform Blocks used to allow Uniforms to be inlined as Constants

• Provides a Platform for additional features

  • Anisotropic Filtering + MSAA
    • Will require Unstitching for Atlases > maxImageArrayLayers in size
    • Atlases < maxImageArrayLayers can be optimized into onion textures
  • Allow AMD/Intel GPUs to use > 512x Resource Packs
    • Will likely use the same features as above to unstitch atlases
    • if implemented, The new max resource pack limit for AMD/Intel would likely become 2048x

issues:

• Doesn't work on Mac/MoltenVK due to Texture Slot limits (Fixable: Needs a Bindfull fallback)
• Postprocess renderpasses are not functional yet (Fixable w/ Pushing new Descriptor allocations)
• Broken MVP rotations when entering the End
• Player hand lighting glitches
• Teleporting in some instances causes outdated MVP rotations
• Has not been tested fully on AMD/Intel Devices

Required Vulkan 1.2 and 1.3 features

• inlineUniformBlock
• runtimeDescriptorArray:
• descriptorBindingPartiallyBound:
• descriptorBindingVariableDescriptorCount:

Going to replace this with a cleaned up PR in a few days, without all the N/A commits/optimizations.
