Modern vanilla linear fog rendering & Fixes

[HaHaWTH]

This pull request brings a new water fog rendering mode to AA, linear fog rendering. Backported from Minecraft 1.21.7, the default one is AA's EXP2 fog rendering, users can switch between these two modes.

Changes

Linear Fog

• Basic linear fog rendering logic
• 15% view distance reduction when in swamp biomes
• Dynamic scale fog distance based on view distance
• Cylinder fog when view distance < 96 blocks (Not possible at 1.12.2, requires modern GL features)

Fix

• Blindness factor is incorrectly calculated with current time in milliseconds, which should use potion duration.
• Fix weird black edges near the chunk border (caused by skybox rendering) (disabled by default)
