Disable antialiasing for all fonts loaded via Lua API

Browse Source 
All pixel fonts and TTF fonts loaded through RL.LoadFont(),
RL.LoadFontEx(), RL.LoadFontFromImage(), and RL.LoadFontFromMemory()
now use TEXTURE_FILTER_POINT instead of the default bilinear filtering.

This ensures crisp, pixel-perfect rendering without blurring for
pixel art fonts and maintains consistency across all font loading
methods in the game engine.
