Also updates Cubyz-libs after PixelGuys/Cubyz-libs#28 and PixelGuys/Cubyz-libs#27 to validate the CI-generated libraries

fixes #3541
fixes #3543

It appears to be more complicated than I thought it would be, I'm not sure how to work with extensions in MoltenVK, and I'm not going to remote-debug this. Someone who actually has a Mac will have to it when the time comes for #299.

[blackedout01]

@IntegratedQuantum Are you referring to vkCmdPushDescriptorSetKHR? This function got promoted to be part of Vulkan 1.4 and as MoltenVK implements this version, it can just be used as vkCmdPushDescriptorSet when compiling for macOS.
A quick fix would be the following:

if (builtin.target.os.tag == .macos) {
    c.vkCmdPushDescriptorSet(self.handle, @intFromEnum(bindPoint), pipeline.pipelineLayout, 0, @intCast(writeInfo.len), writeInfo.ptr);
} else {
    c.vkCmdPushDescriptorSetKHR(self.handle, @intFromEnum(bindPoint), pipeline.pipelineLayout, 0, @intCast(writeInfo.len), writeInfo.ptr);
}

But it's repetetive, could you suggest a prettier version?

[IntegratedQuantum]

Yes, that's true for this extension, but in the future I would like to support other extensions as well, like VK_EXT_fragment_shader_interlock #817 which is not in any core version.
So I would like to do it properly for this extension, so that we have extension loading set up properly when the time comes for implementing #817.

I tested this on my machine and this is the error I got:

replacing that library file's INFINITY with std::numeric_limits<_RealT>::infinity() gives me this new error:

@Vexo413 this PR is only about testing macos and compilation in the CI, so I'll merge it now.
Note that macos will still not actually run, due to missing OpenGL support. If you want you can test it again and make a new issue if you still get the same compilation error.
