Erik Kurzinger ce03b8b3b1 LibGfx+LibWeb: Only compile dma-buf-related code on Linux
Shareable Vulkan image allocation on Linux relies on the dma-buf
interface, which is a Linux-specific thing. Therefore, we should only be
compiling it (and any code that uses it) on Linux. This change adds
preprocessor guards to do that. Enabling similar functionality on other
operating systems will need to leverage analogous interfaces on those
platforms, e.g. win32 handles on Windows.

All Vulkan image code will now be guarded by the USE_VULKAN_IMAGES
preprocessor definition, currently enabled on Linux if Vulkan is
available. Additionally, we shuffle around some code in
OpenGLContext.cpp to simplify the preprocessor conditionals.
