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: refactor into vo_gpu This is done in several steps: 1. refactor MPGLContext -> struct ra_ctx 2. move GL-specific stuff in vo_opengl into opengl/context.c 3. generalize context creation to support other APIs, and add --gpu-api 4. rename all of the --opengl- options that are no longer opengl-specific 5. move all of the stuff from opengl/* that isn't GL-specific into gpu/ (note: opengl/gl_utils.h became opengl/utils.h) 6. rename vo_opengl to vo_gpu 7. to handle window screenshots, the short-term approach was to just add it to ra_swchain_fns. Long term (and for vulkan) this has to be moved to ra itself (and vo_gpu altered to compensate), but this was a stop-gap measure to prevent this commit from getting too big 8. move ra->fns->flush to ra_gl_ctx instead 9. some other minor changes that I've probably already forgotten Note: This is one half of a major refactor, the other half of which is provided by rossy's following commit. This commit enables support for all linux platforms, while his version enables support for all non-linux platforms. Note 2: vo_opengl_cb.c also re-uses ra_gl_ctx so it benefits from the --opengl- options like --opengl-early-flush, --opengl-finish etc. Should be a strict superset of the old functionality. Disclaimer: Since I have no way of compiling mpv on all platforms, some of these ports were done blindly. Specifically, the blind ports included context_mali_fbdev.c and context_rpi.c. Since they're both based on egl_helpers, the port should have gone smoothly without any major changes required. But if somebody complains about a compile error on those platforms (assuming anybody actually uses them), you know where to complain.

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.

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: 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.
