* Add zig buildfile for examples.

- `zig build` to compile all examples
- `zig build [module]` to compile all examples for a module (e.g. `zig build core`)
- `zig build [example]` to compile _and run_ a particular example (e.g. `zig build core_basic_window`)

You can use `-Dtarget=` to compile for a non-native platform, such as
`zig build -Dtarget=x86_64-windows-gnu` to compile from Linux to
Windows.

* Skip pthread example on Windows.

* Select appropriate lib file based on target.

It seems vox loader is not working properly...

* Add DrawCylinderEx and DrawCylinderWiresEx

* Modify examples/models/models_geometric_shapes.c to show the
usage of DrawCylinder(Wires)Ex

* Simplified DrawCylinder and DrawCylinderWires to use the -Ex versions.

* This reverts commits f49b2598dd and
4542b32e4e.

* Fixed formatting.
Renamed base_angle to baseAngle.
Remove most of the raymath.h calls.

* Added check for empty cylinder.

* Added check for empty cylinder.

* Fix bug.

Removed unneeded resources to use raylib ones.

* Move older and abandoned bindings to new section at the end of the file

* cleanup

* raylib forever is auto

raylib was using `stb_perlin.h` library to generate perlin noise, it seems that recently this library has been flagged as it could be infringing some algorythm patent. For security, it has been removed from raylib.

`RLGL.State.vertexCounter` is a generic counter and it's reused for all `rlRenderBatch`, actually, once render batch is filled, required vertex count is provided through the draw calls, so, the total accumulated count of vertices is not directly registered inside the rlRenderBatch.

`RLGL.State.vertexCounter` keeps that count but one possible improvement(?) could be moving the `vertexCounter` inside `rlRenderBatch` to always keep a register of the total accumulated vertices in that batch (despite that info is provided by the accumulated `draws[i].vertexCount`.

Simplifying, `RLGL.State.vertexCounter = SUM(draws[i].vertexCount)`

The decision to move the counter out of `rlVertexBuffer` is to keep only the data that I think should belong to `rlVertexBuffer` and make it more generic, aligned with raylib `Mesh` structure.

The decision to not add it to `rlRenderBatch` is because it could contain multiple `rlVertexBuffer` and it would be confusing (because it would only register the count of the last filled one).

Instead of registering vertex texcoords and colors on every call, we keep the last defined value and we record everything on `glVertex*()`. Actually that behavior is aligned with OpenGL 1.1 standard.
