Revert of Finish OSMesa support for Ozone X11.

Revert of Finish OSMesa support for Ozone X11. (patchset #2 id:40001 of https://codereview.chromium.org/2730993002/ )

Reason for revert:
Sorry, speculatively reverting based on persistent ozone builder flake. Started with this CL as best as I can tell.

Appears to be a sync command buffer IPC hang on shutdown, affecting only tests which force single-process mode. Possibly a deadlock caused by ... something in the OSMesa/X11?
