Change SDL backend to restore the original GL context. This allows Qemu's virtio-gpu to support new virglrenderer async-fencing feature for Virgl contexts, otherwise virglrenderer's vrend creates a fence-sync context on the Qemu's main-loop thread that erroneously stays in-use by the main-loop after creation, not allowing vrend's fence-sync thread switch to this new context that belongs to it.

It allows Qemu to handle fence as soon as it's signalled instead of periodically polling the fence status. This feature is required for enabling DRM context support in Qemu because legacy fencing mode isn't supported for DRM contexts in virglrenderer.
