Depend on libglvnd instead of mesa to import GL(ES) symbols #6238
Description
Currently many packages that requires OpenGL API are marked as depending on mesa1. However, the vendor-independent GL API libraries (libEGL.so, libOpenGL.so, and libGLESv2.so) are all provided by libglvnd. Packages don't need to have ABI dependencies on mesa directly, but usually rather import libglvnd libraries, and rely on it for the dispatching work.
We should replace mesa with libglvnd for such packages. It should be left for the user to decide the GL implementation to use.
