Update renderer integration for new pipeline API

[temotskipa]

Summary

• remove the outdated RenderSystem vertexSorting access widener and rework RenderSystem mixin hooks to read the new GPU uniform buffers
• add a DynamicUniforms mixin and MatrixUniformBuffer helper so dynamic uniforms and projection matrices keep the Vulkan state in sync with Minecraft's new render pipeline
• switch UI utilities, fog/light handling, and uniform suppliers to use the refreshed VRenderSystem state, including new fog/game time tracking helpers

Testing

• ./gradlew genSource
• ./gradlew build (fails: legacy GL mixins need retargeting after the rendering refactor)
