eglfs: Support virtual desktops in the OpenGL cursor

The GBM-based hardware cursor already has this. Let's implement it
in the commonly used OpenGL cursor too. The main user will be the
EGLDevice backend which does not currently have a hardware cursor
but supports multiple screens.

This also means QEglFSCursor must be capable of operating on different
contexts (and what's more, non-sharing contexts).
