Successor to that old MoltenVK PR. Does a lot of cleanups within root CMakeLists.txt, hands over MoltenVK and VulkanValidationLayers to CPMUtil, and separates out common operations into my modules. Hopefully reduces the monstrosity that is root CMakeLists.txt. Please test: - builds on all platforms - VulkanValidationLayers Signed-off-by: crueter <crueter@eden-emu.dev> Reviewed-on: https://git.eden-emu.dev/eden-emu/eden/pulls/3126 Reviewed-by: Lizzie <lizzie@eden-emu.dev> Reviewed-by: CamilleLaVey <camillelavey99@gmail.com>

# otherwise grabs stuff from Git.
