This reverts commit cfb81e4a00.

This reverts commit 32e7732061.

[utils] was created long time ago, when [rcore] contained all the platforms code, the purpose of the file was exposing basic filesystem functionality across modules and also logging mechanism but many things have changed since then and there is no need to keep using this module.

 - Logging system has been move to [rcore] module and macros are exposed through `config.h` to other modules
 - File system functionality has also been centralized in [rcore] module that along the years it was already adding more and more file-system functions, now they are all in the same module
 - Android specific code has been moved to `rcore_android.c`, it had no sense to have specific platform code in `utils`, [rcore] is responsible of all platform code.

* fix small typo

* other small typos

This is necessary to allow for using the function in dependent `build.zig`s.

These changes will be required by Zig version 0.15.0.

build.zig doesn't support the examples for the emscripten OS but it does
support the raylib library. However, the examples panic if emscripten
is configured which prevents it from building the library. I've replaced
this panic with a fail step to fix this.

Previously, the libc paths file `android-libc.txt` was written to
the folder from which the user ran `zig build`. This caused
problems when using raylib as a dependency in other zig
projects, since raylib is not built in the project root, but the
`android-libc.txt` file was still generated in the project root. The file
should now be generated in .zig-cache, which should fix the isssue (and
leave the project root folder cleaner).

Added an Android target to the zig build script.
This allows a user to easily build with only Android-supported
libraries.
Library paths are automatically inferred as much as possible.

It looks like raylib doesn't require rglfw.c if you're using the RGFW
backend.  I'm guessing the same is true for SDL but I haven't tested.
Excluding this one file brings the raylib library down from 6.9 MB to
6.3 MB for RGFW.

However, one of the examples requires the symbols from rglfw.c,
to accomodate this I added a function that will check whether raylib has
already included rglfw and if not include it for that one example.

Removes the second build.zig in the examples directory and incorporates it
into the main build.zig. This gives the zig build system the data needed to
know if the raylib library needs to be rebuilt when running any example.

Is now possible to switch platform

Is now possible to diable raudio, rmodels, and so on

Made getOptions public so it can be used for zig wrappers

function

- addRaylib just duplicates what adding raylib as dependency already does
  so it do not needs to exist
- move raygui build to standard build process when flag is enabled. this
  works correctly when using raylib as dependency and having raygui as
  dependency as well. problem with previous approach was that raygui was in
  options but it was doing nothing because you had to also use addRaygui for
  it to be effective
