Retracing EGL trace on windows

[José Fonseca]

EGL is not supported on Windows.  Only WGL is.

There was a half baked attempt to support it on
https://github.com/apitrace/apitrace/commits/angle

But unless you really must use Windows, I'd just recommend using the same
or another EGL emulator on Linux.
