Update to 1.21.11

[HalbFettKaese]

Base game updates that were adapted in objmc with this PR:

• Block positions are stored in world space rather than player space. The old uniforms now no longer exist, this made blocks unable to render.
• The game now uses more advanced LOD on block textures. Neglecting to implement this made all blocks look blurry, and objmc textures now use texelFetch to avoid the seams at the model edges becoming visible on lower LOD.
• Entities now can have different lighting on the front and back. Objmc lighting now has directly adapted this change.
