112b416056 Implement new CPU lightmapper
Completely re-write the lightmap generation code:
- Follow the general lightmapper code structure from 4.0.
- Use proper path tracing to compute the global illumination.
- Use atlassing to merge all lightmaps into a single texture (done by @RandomShaper)
- Use OpenImageDenoiser to improve the generated lightmaps.
- Take into account alpha transparency in material textures.
- Allow baking environment lighting.
- Add bicubic lightmap filtering.

There is some minor compatibility breakage in some properties and methods
in BakedLightmap, but lightmaps generated in previous engine versions
should work fine out of the box.

The scene importer has been changed to generate `.unwrap_cache` files
next to the imported scene files. These files *SHOULD* be added to any
version control system as they guarantee there won't be differences when
re-importing the scene from other OSes or engine versions.

This work started as a Google Summer of Code project; Was later funded by IMVU for a good amount of progress;
Was then finished and polished by me on my free time.

74e224f2c7 GLES2: Add comments around EXT_shader_texture_lod check
To avoid reintroducing bugs as I did in #26928 and #26932.

texture2DLodEXT and textureCubeLodEXT are only for the fragment shader with
https://www.khronos.org/registry/OpenGL/extensions/EXT/EXT_shader_texture_lod.txt
In the vertex shader, texture2DLod and textureCubeLod are built-in.

f5f565e3e4 GLES2: Ensure extension checks for texture2DLod
In canvas.glsl and scene.glsl, we were using texel2DFetch from stdlib.glsl,
which uses texture2DLod. In both cases, the stdlib.glsl include came before
the define of texture2DLod.

Might fix issues for drivers that don't support GL_EXT_shader_texture_lod.

57416bfbce GLES2: Define 'lowp' for OpenGL 2.1
Precision qualifiers are only used on OpenGL ES 2.0 and 3.0,
and while OpenGL 3.3 defines them for compatibility (but without
practical effect), they're missing from OpenGL 2.1, so we define
them to prevent compilation errors.

Fixes #24521.
