This is a re-do of [1]. Enable EGL_EXT_image_dma_buf_import_modifiers with EXT_image_dma_buf_import. This allows users to use queryDmaBufFormats to query the list of supported formats even if modifiers are not supported. With this change, queryDmaBufModifiers always returns zero modifiers. A compositor survey reveals that this should be fine: wlroots [2], Weston [3], Mutter [4] [5], kwin [6] and xorg-xserver [7] seem to all support this case gracefully. Tested with Sway and wlroots by running weston-info and checking the list of formats advertised by zwp_linux_dmabuf_v1. Also ran weston-simple-egl and checked zwp_linux_dmabuf_v1 was used instead of wl_drm.
