* 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).
