It would try to use the glfw on the system but we're cross-compiling for web where the implementation is provided by emscripten's team

* Updated rcore.c, renamed 'time' to 'time_nsec'

When PLATFORM_ANDROID, PLATFORM_RPI or PLATFORM_DRM were defined, there is a compilation error to redefinition of the variable 'time', so the second instance of 'time' was changed to 'time_nsec' which both fixes the name collision and more accurately describes what that variable represents.

* Renamed 'time_nsec' to 'nanoSeconds'

This breaks other values of the struct.

* Use const for pointer float array

* missed a definition

* JSON parser: Use array for function params (#2255)

* Parser: follow C convention of type before name

* Update file names in build scripts

* Rename lighting_instanced shader to instancing

Reviewed formating to follow raylib coding conventions.

rlCullFace sets the face culling mode to RL_FRONT or RL_BACK which correspond to GL_FRONT and GL_BACK respectively.

Added a comment explaining the range limitations of GetRandomValue.
Added a run-time warning TRACELOG when GetRandomValue is called with an invalid range.

Those two functions have been moved to a new example: `models_draw_cube_texture`. The reasons for this decision:
 - Function inflexibility: Many users with the need to draw a textured cube could need to customize the texture applied to every face, that function did not allow that kind of functionality.
 - rlgl functionality exposure: The implementation exposed will teach users how to implement custom textured triangles drawing.

Now Raylib-py is a releases-only project.
For now on, code maintenance will happen in a parallel project created to automate the binding generation: RaylibpyCtbg

This function implementation has been moved to the related example. Current implementation can be probably customized depending on user needs.

This function can be easely replicated using `DrawtexturePro()` and actually it was doing some assumptions not transparent to the user. Even the function name was confusing. No example was available for it and actually noone requested one example.

Function moved to `examples/textures/textures_polygon.c`, so users can learn from the implementation and create custom variants as required.

When building a x86 project, the folder inside lib is named i686. However Android x86 actually expects the folder to be called x86.

* Improved billboards example, highlighting rotation and draw order

* changes to conform to the raylib conventions

* NOW it conforms
