vo_opengl: x11egl: retrieve framebuffer depth This is used for dithering, although I'm not aware of anyone who got higher than 8 bit depth support to work on Linux. Also put this into egl_helpers.c. Since EGL is pseudo-portable at best I have no hope that the EGL context creation code in all the backends can be fully shared. But some self-contained functionality can definitely be shared.

vo_opengl: factor some EGL context creation code Add a function to egl_helpers.c for creating an EGL context and make context_x11egl.c use it. This is meant to be generic, and should work with other windowing APIs as well. The other EGL-using code in mpv can be switched to it.

vo_opengl: egl_helpers: add a way to pass more options For X11 garbage we have to pass some annoying parameters to EGL context creation. Add some sort of extensible API, so that adding a new parameter doesn't break all callers. We still want to keep it as a single function, because it's so nice isolating all the EGL nonsense API boilerplate like this. (Did I mention yet that X11 and EGL are garbage?) Also somewhat simplifies the vo_flags mess in the helper internals.

vo_opengl: egl_helpers: add a way to override config selection Preparation for the following commits. Since at least theoretically the config selection depends on the context type (EGL_RENDERABLE_TYPE has separate bits for ES 2, ES 3, and desktop GL), doing it any other way would be too painful.

// defaults to 0 (they are sorted by eglChooseConfig)

vo_opengl: add a generic EGL function loader function This is pretty trivial, but also quite annoying due to details like mismatching eglGetProcAddress() function signature (most callers just cast the function pointer), and ARM/Linux hacks. So move them all to one place.
