libs: egl: surface: export EGLImage as DMABuf if GEM not supported
This code path is used when frames are rendered as textures through GstVideoGLTextureUploadMeta with EGL, mainly under Wayland. Originally the EGLImage was exported as GEM, which was handled by Intel drivers, but Gallium ones cannot create VA surfaces from GEM buffers, only DMABuf. This patch checks the memory types supported by VA driver to choose the render the EGLImages from GEM or DMABuf, because GEM is still better where supported. DMABuf is well handled either by intel-vaapi-driver and gallium. Fixes: #137 Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer-vaapi/-/merge_requests/122>
