backends/native: Stop supporting stage views being disabled

Browse Source 
Get rid of some technical dept by removing the support in the native
backend for drawing the the whole stage to one large framebuffer.
Previously the only way to disable stage views was to set the
MUTTER_STAGE_VIEWS environment variable to 0; doing that now will cause
the native backend to fail to initialize.
