context_drm_egl: Introduce 30bpp support
This introduces the option --drm-format (currently used only by context_drm_egl, vo_drm implementation is pending) which allows you to pick between a xrgb8888 or a xrgb2101010 visual for --gpu-context=drm. Requires a recent mesa (18.0.0_rc4 or later) to work. This also fixes a bug when using --gpu-context=drm on a 30bpp-enabled mesa (allow_rgb10_configs set to true). Previously it would've set up an XRGB8888 format at the DRM/GBM level, while a 30bpp EGLConfig would be picked, resulting in a garbled image.
