build: make GBM optional Now that the DRM backend no longer depends on GBM, we can make it optional. The GLES2 renderer still depends on it because of our EGL device selection. This is useful for compositors with their own renderers, and for compositors using the Vulkan renderer.

allocators = get_option('allocators')
if 'auto' in allocators and get_option('auto_features').enabled()
render/allocator: add udmabuf allocator udmabuf can create a DMA-BUF backed by a memfd. This is useful when running with a software implementation of GL/Vulkan: the memfd can be passed to the parent compositor via wl_shm and the DMA-BUF can be imported via the usual APIs into GL/Vulkan.
