This makes possible implementation of multi-window support in SDL2.

According to @Daft-Freak from SDL2 port, this PR should be reworked, so for every "window" a separate canvas be created to not mess things up when GL is used. Now this PR should be considered suspended for a while. |

In my port of QEMU to JavaScript I use their SDL2 UI for graphics. Previously, I had to disable every window except one, otherwise the canvas was messed up. There is also an issue #5081 on this topic.
In this PR I add the basic support for window selector to Emscripten. SDL2 support requires separate PR to its repository, though: emscripten-ports/SDL2#55.
PS: Frankly speaking, I'm not familiar with OpenGL at all, but it seems to work in my QEMU port. Corrections are welcome, of course.
