CMake: Remove USE_WAYLAND option

[M374LX]

With GLFW now having both X11 and Wayland enabled by default, the USE_WAYLAND CMake option is no longer necessary.

Setting GLFW's own CMake options GLFW_BUILD_X11 and GLFW_BUILD_WAYLAND to OFF allows either to be disabled.

This PR additionally includes a check to prevent both from being disabled.

@M374LX Thanks for the review! It seems this change is generating some issues in the CI build system...

[M374LX]

@raysan5 The CI fails with the message:

Failed to find wayland-scanner

This means that the wayland-scanner utility is missing in the machine that runs the build test, but installing it should fix the problem. On Debian, for instance, the package to be installed is libwayland-bin.

sudo apt-get install -y --no-install-recommends libglfw3 libglfw3-dev libx11-dev libxcursor-dev libxrandr-dev libxinerama-dev libxi-dev libxext-dev libxfixes-dev

Adding libwayland-bin here would be the solution, I guess.

But now I'm questioning - doesn't the Makefile need this too?

[raysan5]

@M374LX Added libwayland-bin to CI system for linux builds.

@Peter0x44 Afair, Makefile does not manage those deps, are expected to be installed in the system by user.

[Peter0x44]

@raysan5 I was talking about the ci system for the makefile

[raysan5]

@Peter0x44 Oh, ok, I think I already modified it. Just reviewed CMake build CI.

[M374LX]

@Peter0x44 There is a deeper issue affecting the Makefile and the Zig build system (#3850), which I plan to review too.
