feat(render3d): texture filtering and shadow resolution a game can change while it runs

Browse source 
- r3d_set_anisotropy(level) updates every mipmapped texture already loaded (OpenGL parameter,
  Vulkan sampler record), not only later uploads; the game's setting never reached the scanned
  materials, which load before the settings are read.
- shadow_set_res(size) remakes the cascades at 1024 / 2048 / 4096 (shadow_res replaces the
  SHADOW_RES constant); lighting.glsl reads the texel size from the map, so OpenGL frames at
  2048 are unchanged.

**Texture filtering and shadow resolution as settings a game can change while it runs.**
- `r3d_set_anisotropy(level)` sets the anisotropic filtering of every mipmapped texture already
loaded, not only of later uploads, on OpenGL and Vulkan.
- `shadow_set_res(size)` remakes the cascades' depth layers at 1024, 2048 or 4096 (`shadow_res`
replaces the `SHADOW_RES` constant); the lighting reads the texel size from the map.
