gdkglcontext-win32-wgl.c: Fix Cairo fallback check

Browse Source 
We were setting the WGL pixel format in GdkWin32Display too early, so the code
does not bail out correctly when we retry establishing the WGL context.

Fix this by pushing back setting the WGL pixel format only after it passes the
shader availability check.

Should fix issue #4257.
