* 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

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.

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

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.

This adds `ImageDrawCircleLines()` and `ImageDrawCircleLinesV()` to draw outlines of circles, and updates `ImageDrawCircle()` draw a filled circle to match the effect of `DrawCircle()` and `DrawCircleLines()`.

raylib library tries to avoid `long long` usage. Several SSBO functions have been reviewed (including some renames for consistency) to minimize `long long` type usage.

This simplification will allow the usage of `rshapes` as STANDALONE mode in a future. Only a small set of `rlgl` functions are required and they can be "more" easely replaced if no `rlPushMatrix()`/`rlPopMatrix()` are involved.

More simplification planned for the future, maybe the textures dependencies.

This linkage is only required for arm 32bit but I don't know how to detect that specific architecture in the Makefile...

This reverts commit 4f6fbaed41.

Specifically, std.fs.OpenDirOptions struct no longer has the iterable
flag, now it's a standalone function call std.fs.openIterableDir
