fix(Library/Sys): Load pojavexec at the right time

Usually LWJGL3 programs would run Library.initialize() to make sure
LWJGL is loaded first. We put pojavexec here because it provides methods
that modules may need. Currently GLFW and Vulkan modules have methods
that are needed by pojavexec, those being `getVulkanDriverHandle()` and
`nativeInitializeGLFWNativeBridge()` the latter of which is found used
in the Amethyst-Android repository.

LWJGL2 programs run through LWJGLX load Sys.initialize() instead so we
also add it there for the same reason.
