ci: mingw build target to cross compile EFL for Windows

We are using the EFL windows package installer (ewpi) from Vincent Torri
here (thanks!) to setup all the needed cross compiled dependencies for
EFL.

The make target is disabled as we are not able to execute the windows
binaries withour additional work to run check.

Work is ongoing in ewpi to have the dependencies provided for soem of
the disabled build options (gstreamer, webp, tiff, physics, etc). Once
these are working well in ewpi we will enable them here as well.
