Alex Shvartzkop 3fa40e05dc Use GLAD for OpenGL loading instead of GLEW.
This allows us to pick GLX on X11 and EGL on Wayland
at runtime when building with wxWidgets 3.3.2+

GLEW only allowed to choose between GLX/EGL at compile time.

This also removes KICAD_USE_EGL option, KiCad will use
whatever wxWidgets was built with.
