FindOpenGL: Default to non-GLVND libraries for legacy GL
Projects using `OPENGL_LIBRARIES` or `OpenGL::GL` expect legacy GL.
Although GLVND OpenGL+GLX provides legacy GL interfaces, using those
library files may conflict with legacy GL library files used by
dependencies (or dependents) of such projects. Therefore we should
not yet use OpenGL+GLX when a legacy GL library is available.
If `OPENGL_gl_LIBRARY` is set then use it as the legacy GL library.
If it is *not* set then fall back to using GLVND OpenGL+GLX to provide
legacy GL interfaces. This will allow users to build projects using
GLVND even if they have not been ported.
Fixes: #17437
