Currently, a warning about _GNU_SOURCE being redefined is emitted when
compiling rglfw.c

In file included from rglfw.c:99:
external/glfw/src/posix_poll.c:27:9: warning: "_GNU_SOURCE" redefined
   27 | #define _GNU_SOURCE
      |         ^~~~~~~~~~~
<command-line>: note: this is the location of the previous definition

This can be avoided by not defining _GNU_SOURCE on the command line for
this file.

Defining feature test macros in source code is not really good practice
so this should probably reviewed in glfw itself, at least to maybe check
 #ifdef _GNU_SOURCE first. But for now this change will suffice.

Fixes #4725

Cmake warn remove

* Fix HalfToFloat() and FloatToHalf() dereferencing issues with an union

* Remove unnecessary initialization

* Moved the union to inside the functions

* Fix gamepad SDL_JOYDEVICEADDED and SDL_JOYDEVICEREMOVED event handling for PLATFORM_DESKTOP_SDL by adding joystick instance id tracking

* Fix gamepad button handling

* [rtextures] Only build cubemap mipmaps when necessary

* [rtextures] Assign correct mipmap count to cubemaps

* Add shaders_rounded_rectangle example

* Minor tweaks to example template (add star, more)

* Combine shaders

* Fix changes after review

When asking Makefile to create SHARED library for WEB
	$ make TARGET_PLATFORM=PLATFORM_WEB RAYLIB_LIBTYPE=SHARED
it would instead silently create STATIC library
thus not fulfilling the request as expected

This commit adds an error in this case and stops further execution.

This is not consistent with Cmake, because Cmake throws the warning and
does not stop, but Cmake can easily recover from this case and people
probably does not even notice it. However, Makefile is something that
you have to handle yourself and you have to recover from any issues so
having an error and aborting with exit code 1 is more expected.
Otherwise people may spend a lot of time debugging Makefile in order to
understand what's even going on.

define STBIR_NO_SIMD when __TINYC__ is defined so stb_image_resize2 will
not include *mmintrin which are not supported by all compilers.

There are similar checks for __TINYC__ already elswere in raylib
and they are also mostly there to disable SIMD headers.

Additionally, move similar check for stb_image, to be a little bit
deeper. Before it was defining STBI_NO_SIMD without including stb_image
It was also clashing with note, causing said note to make no sense.

This change is replacing the hardcoded "#canvas" element references in
rcore_web to allow using canvas elements that use different names
(which is necessary when using multiple canvas elements on one page).

Also adding a cursor hiding example to mouse example.

The bindings from @EmmaTheMartian were moved to official status, so the link is updated. 
The name was normalized to be consistent with other 'vendored' names in other languages.

Closes #4673

It generates multiple issues: https://c-faq.com/ansi/constmismatch.html

Fixed: g-buffer textures binding
Fixed: Clearing screen with white would leak onto g-buffer textures
