gitlab-ci: Add MinGW build job.

A rudimentary job, just to ensure Windows builds don't go south.

The FreeGLUT dependencies are derived from the Linux headers plus a .def
file, to avoid any further downloads whatsoever.

v2: Quote all bash variable expansions and treat unset vars as errors,
per Eric Engestrom.

egl: pack all strips per gear into a single draw

We can pack multiple triangle-strips into a single draw, by inserting
degenerate triangles between them. This should be a big win in terms of
CPU usage.

To avoid inserting needless degenerate triangles to invert face-winding,
we can manually invert the order of the back-face as well as emit the
inner face last. This ensures every strip starts with the right
face-winding.

Use glad instead of GLEW.

glad is a more modern, cleaner, and flexible alternative to GLEW. In
particular it has first-class citizen support for OpenGL ES end EGL.

Glad can't be used just for defines. For old demos which only need
defines, we could bundle Khronos glext, but for now place the necessary
defines on gl_wrap.h

wgl/rtotex: Remove.

This sample is broken, it's not easy to fix, and it's too
complicated/niche to be worth the hassle.

egl: use smooth normals for inner face

glxgears smooth-shades the inner face, so let's do that here as well for
visual parity.
