package/kodi: Rework windowing support options
To prepare the bump to the next Kodi version 18.0-Leia we rework the
options to control the windowing platform Kodi is built for. An
automatic choice will no longer be suitable after addition of support
for wayland and gbm, the former also providing a choice to use either
OpenGL or OpenGL ES.
This patch introduces a new choice option by converting the current
X11-based OpenGL support to the new scheme. Other windowing platforms
will be added by subsequent patches.
